For nearly 130 years, Neauphle-le-Château was home to the production of Grand Marnier, right in the heart of the village. Closed in 2012, the factory was long the pride of the town. Throughout the day, it emanated a powerful aroma of bitter orange, the essential ingredient of this spirit, one of the best-selling in the world.

In the heart of the village of Villiers Saint Frédéric, a porch marks the entrance to the old castle. It leads to the old town hall, now the municipal library, and to the church. Behind us, the new town hall.

Astonishing notable house decorated with bricks, probably from the 18th century, with its 19th century turret with a bell-shaped roof, in a beautiful park crossed by the Elancourt stream and surrounded by a high boundary wall.

Strange to find this paved path between fields and small woods. No reliable information found. It could be either a Roman road (but the paving stones seem little worn and the path is not very wide) because Jouars Pontchartrain was a renowned city under Roman Gaul, or an ox path, the gap in the paving suggesting that it was intended to facilitate the passage of carts.

Jean Omer Marie Gabriel Monnet (born November 9, 1888 in Cognac, France, † March 16, 1979 in Bazoches-sur-Guyonne, Yvelines department near Paris) was a French entrepreneur. He is considered the pioneer of European unification efforts without ever having been a politician in the sense of an elected official - he was never a head of government or a minister. Monnet is considered one of the founding fathers of the European Communities and is referred to as the “Father of Europe”. (Source: wikipedia)
