Château de Monceaux de Saint-Omer-en-Chaussée

Château de Monceaux sits in the Petit Thérain valley and features protected facades, roofs, and interior rooms including a grand salon, small salon, and library. The overall layout combines living spaces and structured grounds that together form the typical design of a classical country estate.

François Henry d'Hardivilliers commissioned the castle's construction in 1763, and the same family maintained ownership through the centuries. This continuous ownership by one family shaped how the property developed and was maintained over time.

The castle reflects regional architectural traditions of northern France through its gardens and park, both noted in the preliminary inventory of notable French gardens. These outdoor spaces show how landowners of that era shaped their grounds around their homes.

The castle is open to visitors mainly during Heritage Days when special access times are offered to the public. You should check ahead to confirm the site is accessible on your planned visit date.

The entrance portal and structured park section received official monument classification through a decree dated March 18, 1970. This early recognition shows that certain parts of the grounds were protected at a time when such designations were far less common.
