The effectiveness of design and rehabilitation depends on the structural and morphological information of the urban fabric: the proposed typological system emerges from an organizing structure in urban development and renewal. The study aims to examine the inherited urban spatial system of Hungary (1867-1918), in order to present and define an aesthetical heritage evaluation through a typo-morphology of the structural changes. Determination of the typology of the selected settlements’ urban fabric is the basis of the analysis, as-built heritage as an important and valued part of the contemporary urban fabric in the context of the wider aesthetic values. Vizualna i morfološka obilježja važna su za vrjednovanje naslijeđene slike grada, ali su nepotpuna bez sistematizacije i istraživanja odgovarajućih vrijednosti. Učinkovitost oblikovanja i revitalizacije ovisi o strukturnim i morofološkim podatcima urbanog tkiva jer predložen tipološki sustav proizlazi iz strukture urbanog razvoja i ranijih obnova. Cilj je istražiti takav naslijeđen sustav Mađarske između 1867. i 1918. godine kako bi se utvrdilo estetsko vrjednovanje naslijeđa pomoću tipoloških strukturnih promjena. Utvrđivanje tipova urbane strukture odabranih naselja osnova je za analizu graditeljskog naslijeđa kao važnog dijela suvremene urbane strukture u kontekstu širih estetskih vrijednosti. É. LOVRA CULTURAL HERITAGE — POSSIBILITIES FOR SPATIAL AND ECONOMIC DEVELOPMENT PROSTORNE I RAZVOJNE MOGUĆNOSTI KULTURNOG NASLIJEĐA Zagreb, 2015 Proceedings | Zbornik radova INTRODUCTION “In order to define this quality in buildings and in towns, we must begin by understanding that every place is given its character by certain patterns of events that keep on happening there.”1 The period of modern city development in the former Hungarian Kingdom (1867-1918) was the same as the era of economic recovery and reconciliation that followed the Austro-Hungarian Compromise (1867). Through progressive urbanization of the 19th century, mainly due to the intensive development during the second half of the century the Hungarian towns seem to have risen to the Western European standards and the modern image of the city was created. The current built heritage, the inherited city structure, even in many cases with lacking heritage protection, represents a valuable inheritance of the cities nowadays, and combined with the contemporary layers and defines the cityscape. The evaluation of the structural changes and built environment, harmonization with the contemporary urban tissue requires analyses and an advanced multi-layered methodology for zones (types) identification. The used hierarchy determines the guiding principles in the urban development as well as the evaluation of the urban heritage. The conceptual approach of perception could be classified via the image of the city, which has been created through history and requires an individual method of approach in conservation activities. As one purpose of this paper, the typo-morphology and urban heritage evaluation analysis methods are proposed. The urban spaces show the history of past and actual urban stratification, and through historical mapping it is possible to describe the evolution of forms, identify changes and make comparative analyses to find the relationship between the elements of urban space of the Hungarian towns (1867-1918). Fig. 1 The process and the basic elements of the research that lead to localization and objective evaluation of the urban heritage (Source: Author) In case of these cities, the meaning of image/identity has multi-layered views: perpetuity/evolution – difference/similarity – unity/diversity. The research is directed to particular interests: to analyse the urban heritage as urban tissue permanence, able to ground typo-morphological transformations in the sense of identity and image. URBAN MORPHOLOGY AND THE TYPO-MORPHOLOGICAL EVALUATION OF THE URBAN HERITAGE The urban fabric is determined by the interaction between the components (streets, squares and green spaces, public spaces). The morphological basis can be described by socio-technical schemas and typified forms: analysis of maps was chosen to achieve a method for the analysis of urban spaces by looking at characters/identity to describe the historical process of development of the city form and its spatial consequences. Understanding and evaluating the components of the urban context and building an urban fabric type is a case-dependent research, but these can be typified and defined in a semi-general analysis. To evaluate the inherited cityscape and spatial pattern, besides the typo-morphological approach, the assessment has to take into account the principles of the Conzenian hierarchy.2 The cities could be studied in terms of several key elements: land use, building structures, plot pattern and street pattern as identified by Conzen (1960) while stressing the difference in permanency of these elements. According to Larkham (1997), these can be combined at different levels to create a hierarchy inside the city (town plan: maximal/permanent, build environment: considerable/semi-permanent, varying with periods). All these estimations create a hierarchical framework, what can be used to create a city map to evaluate the urban heritage and define the image of the city. The proposed typo-morphological analysis system follows the Conzenian cognitive approach, with a combination of Caniggia’s research methodology (understanding the built form through the historical process). The approach of the study negates the doctrine that each city is unique (Benevolo), establishing rather that each city can be seen as a collage of different urban tissue types, the organization of which creates a specific urban type and image.

LOVRA CULTURAL HERITAGE — POSSIBILITIES FOR SPATIAL AND ECONOMIC DEVELOPMENT PROSTORNE I RAZVOJNE MOGUĆNOSTI KULTURNOG NASLIJEĐA Zagreb, 2015 Proceedings | Zbornik radova Lynch (1960) mentions: “The image of a given physical reality may occasionally shift its type with different circumstances of viewing.”3 Even if the type of the town can be seen by urban physics in the specific semantic rules of architecture, landscape and urban design, the image is more subjective, but can be described via objective factors and rules (according to the Analysis 2 about the image and heritage evaluation). Moudon states: “typo-morphology offers a working definition of space and building type (…) its relationship to the city, and to the society in which it takes place”4. The case study analyses are dealing with the physical and spatial structure of the built environment, based on detailed classifications of buildings and open spaces by type. In our case generalized information about city development is not sufficient, since the Hungarian towns went through a specific evolution during the study period, partially following the Western trends of city-development. In order to apply the complex method in the evaluation of the inherited townscape and extend the scope of the typology, Korpf’s zoning practice5 has to be combined with a single semantic description of the urban elements. Tab. I Analysis 3a: Heritage hierarchy in case of Nagyvárad (Oradea, Romania) Tab. II Analysis 3b: Heritage hierarchy in case of Győr, Hungary Tab. III Analysis 3c: Heritage hierarchy in case of Arad (Arad, Romania) In order to describe and evaluate the inherited townscape to give a proper background of the heritage protection and conservation processes a particular logic was found in the organization of the urban fabric through different periods: some categories remain constant (town plan), certain aspects are less stable (build environment): different levels of permanency can be found by studying the layers. The development of the city is not random, follows rules and creates a hierarchical system since the elements are not separated objects and the relations between elements are essential. Fig. 1 describes the process and the basic elements of the research that lead to localization and objective evaluation of the urban heritage: the urban character is synonymous with the concept of physical identity, built up by urban elements, which create the city’s pattern through their combination, and divide it into zones: physical and functional characteristics define the zones, and the urban fabric typology can be created. BUILT HERITAGE AND EVAULATION: TOWNSCAPE The historical areas are considered to represent cities’ identity via urban facades. In order to conserve the complex heritage of the historical quarters the urban fabric has to be taken into consideration. The importance of protecting the urban heritage of the city has emerged since the ’Declaration of Amsterdam’ (1975) stated that the architectural heritage should include “not only individual buildings of exceptional quality and their surroundings, but also all areas of towns or villages of historic or cultural interest”.6 The ‘Washington Charter’ (1987) strengthened recognition of the qualities to be preserved, since “Urban patterns as defined by lots and streets; Relationships between buildings and green and open spaces”.7 The typo-morphology can solve the problem of identification of the historical areas. An important contribution can be made to the conservation and management of historical urban landscapes by employing the approach of typo-morphology to improve the consideration of the historic urban landscapes as ensembles of defined and detected urban pattern or as an urban fabric zone. CASE STUDIES The proposed complex research method was used to find the aesthetic, heritage values of the cities via studies of typo-morphology, hierarchy and townscape. One of the most significant signs of the modernization progress, besides the progress in infrastructure development, was the regularization of the streets and the increased number of the paved roads, establishment of the transport network. At the beginning of the 20th century the selected towns mostly achieved the character of a western-like city. In case of Oradea and Győr the spatial system, urban pattern and in part the functions of the space syntax changed in the historic city core due to the redevelopment of the inner town, giving the base of the typo-morphological urban heritage evaluation.

TYPO-MORPHOLOGY AND HERITAGE (See: Poster book) Analysis 2 (a-d). TOWNSCAPE – URBAN HERITAGE VALUE (See: Poster book) The historical character and tissue are the important physical background, creating a specific view of town and providing the symbolic meaning of city. Analysis 3 (a-c). HERITAGE HIERARCHY (Tabs. I-III) Layers and hierarchy are added values of the typological approach to urban systematization: the urbanizing elements tend to have variable resistance to change, according to Conzen’s10 practice, if the scheme of the individual form grows in complexity, the resulting map shows a hierarchy of the layers. a) NAGYVÁRAD (ORADEA, RO)8 was created on the riverside of two springs in the crossroad of the plains and the mountains. Its area was 8,305 acres in 1869 and didn’t change significantly until 1914. The analysis of the urban development shows that the main characteristics are different from the type of the Transylvanian towns, shows more similarities with lowland cities, without following the urban development path of the ‘steppe towns’.10 A typical feature of urbanization in the lowland (Alföld) was the “ground floor” urban development, in Oradea the rate of multi-storey houses was 5%. New streets were opened at the place of the channels of the regulated Pece and Paris springs, this type of spatial development can be witnessed in other towns of the former Hungarian Kingdom (Szabadka (Subotica, RS), Győr, Sopron). The spatial pattern of the city changed due to the works at the turn of the 19th and 20th centuries. b) GYŐR (HU),11 in the southern edge of the (Little Hungarian Plain) Kis-Magyar-Alföld has medieval roots, after the demolition of the fortress’ walls (in 1820) the city centre extended till the Market Place and the railway lines (1855) on the South. The greatest modernization force was the industrial development (started in the 1890s), in the 1910s the centre and the Nádorváros were already unified, with the relocation of the Rába’s riverbed the New Town and the Island districts also were linked to the town. c) ARAD (RO) and d) ZENTA (SENTA, SRB) Senta12 is located on the bank of the Tisa river, nowadays in the Vojvodina province, Serbia. The spatial plans from the studied period show amorphous, tree-like road network: three to four principal streets escalated into the Main Square centrally, but peripherally from the West. The city and Arad (RO)13 show similar combined spatial system (more organic street layout in the inner city and joint geometric peripheral urban tissue). CONCLUSIONS The target of the study was to achieve a theoretical and practical way to assess the character of cities via typological system addressed to the evaluation of urban pattern, the townscape and the urban heritage. The town image is shaped by the spatial features and built environment, in conjunction with natural landscape on which it emerged. The urban interaction of the inherited built environment depends on the balance between the traditional and modern, and a certain rhythm in some elements, but the most important is the relationship between the components. The process of identification provides the basis for the quality of visual elements, complexity of space, aesthetic forms, urban public spaces, traditional and modern physical characteristics that influence the image of the city, townscape and the significance of the urban heritage. Through analyzes of the urban zones and pattern, the identification of the historic values was achieved. The analysis was focused on the general image of the area, the relations, the spatial features and the space syntax. The central achievements of the paper is that the study of urban tissue could offer an effective framework for identifying values (pattern of streets, blocks, squares, plots, buildings and architectural style), which are giving historical character of towns and identify the heritage. The outlined methodology offers an identification of zones through the urban tissue contexts, the value and hierarchy based analyses could be used in urban conservation projects to define areas valuable for preservation.

LOVRA CULTURAL HERITAGE — POSSIBILITIES FOR SPATIAL AND ECONOMIC DEVELOPMENT PROSTORNE I RAZVOJNE MOGUĆNOSTI KULTURNOG NASLIJEĐA Zagreb, 2015 Proceedings | Zbornik radova The case studies were selected upon the hydrographical features. In the case of Ordanea and Győr, the cities combine the image of a medieval town, characterized by free arrangement of roads, squares that were formed by widening of the road, with the image of modern 19th/20th century city with planned forms and identity. Senta and Arad show a more complex urban tissue (irregular street network and geometric in the downtown area). The urban heritage of the city, the evaluation of the inherited townscape is defined by physical properties (architecture/urban design values), typo-morphology, continuation, evolution and communication of the forms with the aim of forming a coherent whole. The complexity of the roadways, the visual images and the contrasts resulting from changes in the road network, the built environment, public and green spaces comprise the town image and its perception. The image of the city (identity) has the highest degree in urban physical quality: a specific semantic domain in architecture and urban design (defined by perpetuity/evolution – difference/similarity – unity/diversity).
