In 1799, Montfort becomes the headquarters of a subprefecture and of a district court. 

It was built between 1832 and 1834. 


The building's frontage was willingly built showing its back to the medieval part of the city to illustrate the rupture of the bourgeois elite with the former aristocratic power.

It definitely lost its court function in 2009 and is now the city's  property.

It was rehabilitated in 2014 to house the local multimedia library 'LaGirafe'.
