This building, formerly a castle and count's residence, was transformed into a town hall from 1858 to 1869 by the architect Paul Abadie fils.
The latter has only preserved two towers of the old castle: the polygonal keep built by the Lusignans in the 13th and 14th centuries, and the round tower (or Valois tower) from the 15th century where Marguerite d'Angoulême, sister of François 1492er, was born in 1.
The other parts of the building were built in an eclectic style, in keeping with 19th century tastes and drawing on medieval, Renaissance and classical forms.
Classified Historic Monument since 2013.
