Château d'Agnou, Renaissance castle in Maule, France.

Château d'Agnou is a Renaissance castle in Maule featuring a main front decorated with triangular pediments and vaulted stone ceilings on the ground level. The structure displays typical French 16th century architectural elements with carefully crafted stonework throughout.

Nicolas de Harlay commissioned this castle in the 16th century on the site of an older fortress that was destroyed in 1357 by Charles of Navarre. The new structure rose on this historic location as a statement of Renaissance architecture and family prosperity.

The castle displays French Renaissance design in its facade and decorative details that shaped building practices of its time. Visitors can see these features today in the stonework and window arrangements throughout the structure.

The château is a private co-ownership and cannot be visited inside; there are no guided tours. It stands at the lieu-dit Bout d'Agnou in Maule, Yvelines, and is reached by road. The former gardens, once crossed by paths and footbridges, have all but disappeared, so there is no garden walk to follow.

The dovecote is a cylindrical stone tower with over 3,200 pigeon holes, able to hold more than 6,000 birds, making it one of the largest in the Paris region and one of the oldest in France. The seigneurial privilege of keeping pigeons was abolished in 1790, and the tower emptied for good. It now shelters owls and a family of kestrels.
