Pen Castel tide mill

Pen Castel tide mill is a stone structure along the Gulf of Morbihan coast, stretching roughly 120 meters and built with dimension stone and granite. The complex now houses exhibition spaces and hosts various cultural events.

The building was built in the 17th century as a tide-powered mill and operated for over two centuries. After closing in 1921, it went through various transformations before being restored and converted into a cultural venue.

The structure shows how people once used tidal forces to mill grain and sustain their community. The building reflects how closely local residents lived with the sea and its natural cycles.

The site is accessible from the mainland via a walking path that runs along the coast, offering different views depending on tidal conditions. Pay attention to tidal cycles, as the surrounding area is affected by water levels throughout the day.

The mill was carefully restored in 2009 while preserving its original grinding mechanisms, revealing the precision of historical engineering. These technical details remain visible to visitors, offering direct insight into how grain was once processed.
