Locastel

Already serving as a ford on the Roman road from Vannes to Quimper, the island of Locastel is a strategic point for crossing the Blavet. In the 14th century, the site housed a priory attached to the Abbey of Saint-Gildas de Rhuys. In the 19th century, a lock and lock keeper's house called Langroix were built against it. In 1872, rolling mills and a galvanizing shop for the ironworks were built. This is now a popular site, especially for water sports at the Parc d'Eau Vive de Lochrist.
