Château de Saint-Gratien

Château de Saint-Gratien is a castle with a rectangular main building and a western courtyard in Saint-Gratien, France. The courtyard contains stables, a dovecote, and a neoclassical chapel built from locally quarried chalk.

Jean-Baptiste Jourdain de Thieulloy commissioned architect Rousseau to build the castle, which was completed in 1789. The stone came from the Bavelincourt quarry and reflects the architectural ambitions of the late 1700s.

The facade sculptures were created by François-Joseph Gruau following Rousseau's designs, showing the artistic skill valued during the 1700s. They reflect how wealth and artistic vision came together in the home's appearance.

The castle is registered as a historical monument and includes the main building, outbuilding facades, and a large park on the grounds. Visitors can walk through the estate and view the architectural details of the structures.

General Monash established his headquarters here in May 1918 while preparing for the Battle of Hamel. This episode links the French estate to a significant moment in World War One.
