Préfecture de Lille (Lille Prefecture), Lille

The Lille Prefecture (Préfecture de Lille) is a sprawling architectural site featuring a main building complete with a ceremonial courtyard and adjoining park, alongside two additional wings. At the forefront of the main structure, constructed from hard limestone, stands an elegant fountain. The design follows a Classical style, enriched with numerous allegorical figures adorning the pediments.

This architectural ensemble was developed over the years from 1865 to 1905. The design was spearheaded by Charles Marteau, a notable local architect. The sculpted pediments were crafted by Félix Huidiez, while the garden behind the buildings, which was added in 1874 and is surrounded by a tall brick wall with stone accents, was designed by Georges Aumont, a landscape architect responsible for numerous parks in Lille and Roubaix. In 1905, Léonce Hainez, a regional architect, made additional changes and improvements.

Situated on land that once housed city fortifications (removed in 1865), the site now overlooks the Palace of Fine Arts (Palais des Beaux-Arts), constructed twenty years later. It serves as a critical link between the historic Old Town of Lille and newer areas incorporated in 1858.

The layout of the premises is based on an "H plan," designed to accommodate a variety of functions including the Prefect's residence, office spaces, and rooms for hosting distinguished visitors. The facility also includes areas for various administrative services, a secretariat, and a celebration hall. The interiors are decorated with numerous artworks, including sculptures, paintings, and murals.

Since 1975, the Prefecture building has been recognized as a historical monument.
