Transformation: an EU Project Roman building techniques outside the empire While Roman imports found in graves and settlements outside the empire attest the close trade links between the inhabitants of the provinces and the population on the far side of the frontier, a series of sites with buildings of Roman type indicates the presence of the Romans themselves. One of these is the ca. 50 ha site on the Hradisko at Mušov (CZ). Numerous pieces of military equipment confirm the presence here of Roman soldiers in the years between AD172 and 180, during the Marcomannic Wars.

Black edged: only known through prospection Already in existence by the mid-second century AD was a rectangular timber framed building on dry stone foundations at Stupava, near Bratislava (SK). Attached to it was a walled courtyard. The discovery of a piece of mail armour in the ruins of the house suggests a military use of the building. In the second half of the second century, two new buildings were erected on the same spot. They were linked by a wall to form a complex in the manner Reconstruction of the Roman building at Stupava in the midsecond century Foundations of bath and building 4 Foundation of Building 5 of a simple Villa rustica. The outer timber framed walls were plastered and emplaced in sills of mortared stone. At the turn of the second and third centuries, the courtyard was enlarged and areas within it partitioned to form a typical Villa rustica. The rooms, some equipped with underfloor heating, and decorated with painted plaster, testify to the Romanised lifestyle of the owner. Reconstruction of the Roman building at Stupava in the midsecond century The site at Bratislava-Dúbravka (SK) is an oddity: next to a timber hall-like building, roofed with Roman tiles, a small bath-house was built of mortared rubble, in the way commonly found at villas within the empire. Like all Roman baths it possessed a changing room (Apodyterium) and hot, warm and cold plunge baths (Caldarium, Tepidarium, Frigidarium). But no underfloor heat was supplied to the Caldarium and Tepidarium, so the baths can not have functioned in the Roman manner. Evidently here a Roman building form was being imitated – but without a mastery of the accompanying technology. 20 dition, the mud-brick defensive circuit with defensive ditches (1) and towers (3), and a timber gate (2), are all recognisable as Roman military work. The shape of the site, however, and the interior buildings, are unusual for a Roman fort of this period. The buildings are best paralleled in Roman civil contexts. They include a 21m long timber frame building on brick foundations, with four partly heated rooms close to a set of baths (4); and a building raised on timber sills with apse and colonnaded court (5).
