Remains of the castle of the Counts and Dukes of Savoy

Built on the initiative of Peter II in the mid-13th century, it was a 45 m square enclosure flanked at each corner by a round tower. Its layout is reminiscent of the Château Morges in Switzerland.

Access was defended by a drawbridge over the Bennevy stream. To the north, facing the lake, was the corps de logis comtal. The two-metre-thick, ten-metre-high walls were extended by the town's ramparts down to the shore, punctuated by towers and pierced by four gates. Abandoned by the Counts of Savoy at the end of the 14th century in favor of Ripaille in Thonon, the castle was occupied by the Valaisans in the 16th century, then taken over by troops of the King of France and dismantled in 1591. Three towers, remnants of the castle and ramparts, can still be seen above Rue Nationale.
