The St Maxent mill is a wooden pivot windmill dating from 1630. It is located in the town of Saint-Maxent, in the Somme department, along the Abbeville-Rouen road. You will be able to admire the intact mechanism of the windmill, a rare example of this type in Picardy, and discover the process of making bread from cereals. You can visit the mill with a guided tour or participate in one of the educational workshops organized by the association “Les Amis du moulin à vent de Saint Maxent”. The windmill is open all year round, but you must contact them in advance to make a reservation. Enjoy the panoramic views and fascinating history of this remarkable windmill!

The mill is a little off the road and is no longer intact and has not been renovated.

The 18th-century castle is attached to two towers of an earlier 13th-century castle. More recently it gradually fell into disrepair until 2020 when it found new owners who have been committed to the restoration ever since. Many volunteers also help with this. During our visit we were lucky enough to meet two of them who showed us around the castle and the vegetable garden where very sustainable gardening can be admired. More information can be found on the castle's website https://chateaudebouillancourt.com/
