During the French Renaissance, 1515 into the 1600s, the French never developed their own style architecture, but rather took from other styles to contribute to the various structures that were built or rebuilt during the time. Italian and Roman style architecture is characteristic of the earlier years of the Renaissance, and Gothic styles are seen in buildings that were created later in the times period

The Italian style of architecture during the Renaissance is drawn from classical times and was heavily influenced by Roman temples ( http://www.italianarchitecture.info/HIST.htm
). The structures were very ornate, detailed, and marked by arches, and columns ( http://www.infoplease.com/ce6/ent/A0860693.html
). An example of a building designed in the style of Italy during the French Renaissance is the
Fontainebleau Chateau. This palace was designed by Sebastiano Serlio, a prominent
Italian Architect, who was hired by Francis I.

Serlio’s architecture mirrored the styles of his home country, but also represented symmetry. Serlio had many architectural influences, as he grew up in Italy, was taught art by his father, was trained as an architect in Rome, and then worked in France to develop his own style. Serlio published books about architecture later on that showed heavy influence of classical Rome. Serlio’s styles are the embodiment of French Renaissance architecture (http://www.encyclopedia.com/topic/Sebastiano_Serlio.aspx).
Gothic architecture is grotesque, detailed, and much less symmetrical than ther styles of architecture. Buildings in the Gothic style are marked with detail and sculpture both on the inside and outside ( http://www.discoverfrance.net/France/Art/DF_art3.shtml
).
This style in Paris is often seen in relation to religious buildings. One characteristic of the style is the Saint Eustache Cathedral.

This establishment was created as a church in the name of Saint Agnes, but during the Renaissance period, in the 1500s, was rebuilt to help increase the size of the town square. The cathedral is decorated with arches, pillars, and gargoyle statues. This building is another building that essentially combines architectural styles, which is so characteristic of the French during the Renaissance period.

Another architect who is recognized for his work in Paris during the French
Renaissance is Pierre Lescot. Lescot is credited with designing several influential buildings, including the Hôtel Carnvalet and the Louvre. Lescot’s work is widely representative of the French style of architecture and includes many influences. Lescot was Italian, was trained in Rome, and was trained as an artist by his father. Lescot was hired by Francis I to build a palace in Paris. As it turned out, Lescot added a wing to the
Louvre, a medieval fortress, and made several architectural changes to create the king’s urban palace, which was completed in1546.

Lescot is also recognized as the architect behind the Hôtel Carnvalet. This building was designed as a townhouse for a Parisian politician and is the only remaining mansion in Paris from this time period. The outside walls of the mansion are decorated with Classical style statues, typical of Roman architecture. This mansion was built in
1548, and is open to the public today as a historical museum. ( http://www.parisarchitecture.info/PA-060.htm
