Origin and history

The Town Hall of Etampes is a composite building, born from the fusion of two medieval houses: the house of Saint Christophe (or of the Treille) and another building dating from about 1500, including a salt attic. These buildings, acquired by the city in 1522 and 1538, formed the initial nucleus of the townhouse. The salt attic was demolished in 1847, marking the beginning of a major transformation phase.

Between 1847 and 1850, architects Pierre Magne, Auguste Magne and Daniel Ramée developed restoration and expansion projects. Auguste Magne's final plan, adopted in August 1850 under the advice of architect J. B. Lassus, was executed between 1851 and 1853. The works, led by Pierre Magne, include the construction of the vestibule, the monumental staircase, the library, the council hall and the large living room, marked by sumptuous interior decorations.

The building has an architectural duality: facades and roofs, including those of the 19th century wings, were listed as historical monuments by order of 30 April 1982. The remarkable interior spaces (vestibulum, staircase, library, council room and large living room) have been given additional protection since 9 February 1987, highlighting their heritage value.

The house of the Treille, the former house of Saint-Christophe, and the second medieval house, with its staircase in hors-œuvre, bear witness to the Gothic origins of the monument. Their integration into a neoclassical ensemble in the 19th century illustrates the evolution of municipal needs and architectural tastes, between medieval heritage and Haussmannian modernization.

Today, the Town Hall remains a major civic symbol of Stamps, combining administrative functions and protected heritage. Its central location on the eponymous square makes it a historical and urban landmark for the city and the Essonne department.
