Fort Foucault

Fort Foucault sits between two branches of the Sèvre River and is marked by a neoclassical villa built in 1811 on the remains of an older fortified structure. The building shows how the site transformed from a medieval stronghold into an elegant residential house during the 1800s.

The original complex dates to the 12th century and featured four towers connected to Niort Castle by a drawbridge. These structures protected the river port and monitored shipping traffic in this strategic area.

The house connected to the musical world when composer Auguste Tolbecque ran a workshop restoring instruments on the property during the late 1800s. This activity shaped the place and drew musicians and craftspeople interested in preserving old instruments.

The grounds are open to the public only during European Heritage Days, when the Moulin du Roc organization conducts guided tours of the property. Visitors should check in advance for these dates to plan a visit.

A Renaissance ceramic ceiling with portraits of Henri III, originally displayed at the 1889 World Fair, was later moved to the Bernard d'Agesci Museum. This decorative masterwork shows how the house connected to important artistic treasures and their preservation.
