Tour Saint-Clair, Medieval castle in Derval, France.
The Saint-Clair Tower features a defensive structure rising 24 meters with an upper courtyard and a square lower courtyard protected by ditches.
The castle experienced extensive damage during the Wars of Religion in the late 16th century, leading to its partial demolition under the Edict of Nantes.
The ruins appear in a miniature illustration by Pierre Le Baud in the Chronicles of Brittany, showing the castle's condition at the end of medieval times.
Located 2.5 kilometers from Derval town center, the site includes information panels and remains accessible throughout the year for visitors.
The fortress originally contained nine towers and incorporated a water system with sluices controlling water flow through the surrounding moats.
