Work of Charles Girault, the Petit Palais is designed according to a trapezoidal and ordered four main buildings around a semi-circular garden surrounded by a peristyle ornate.
The Petit Palais has a painted and carved very important, conducted between 1903 and 1925. The architect Charles Girault, who wanted to give his building pomp and dignity of a palace official, had designed a program to glorify the city of Paris and celebrate the benefits of Art. With this intention he had carefully determined the locations of the building for a decoration. Essentially, these are high traffic areas and circulation: vestibules input peristyle garden, cupola stairs. Only two large exhibition galleries were also painted.
More than twenty years have been necessary to achieve these sets.
