The old windmill dating from 1740 in Montfermeil was rebuilt in its original stone form in 1986-88. It is the last of the windmills in Seine-Saint-Denis. The Moulin de Sempin has been awarded the Heritage of Regional Interest label in 2021.
Restored in 1896, it was renamed the "Moulin de la Galette". Originally built on gypsum in the "Sempin" area, it was decided to save this heritage and rebuild it with its own stones, 140 m from its original site... It was inaugurated in 1988 under the name of Moulin de Sempin!
The Moulin de Sempin is open to the public on Sunday afternoons from 3pm to 6pm between early April and early November. For group visits, please contact the Mill for weekday visits (Monday to Saturday).
It now borders a 6-hectare park(Parc Jean Pierre Jousseaume) which was created in 2002. It's an ideal spot for a country picnic, with the flora and fauna having reclaimed their rights!
On-site attractions include the miller's house with its temporary exhibitions, the orientation table, the pond, the donkey meadow and children's playground.
Every year in May, there's a pétanque competition (see their calendar).
The miller's house houses a permanent exhibition on bread, bakery and pastry-making, and shows the different mills in general.
