Plouay is known for its lively markets and shops, and has been an active market centre since the 13th century. Don't miss the opportunity to stroll through its streets. The church of Saint-Ouen, built in the 15th century, has three altarpieces; the first one in tufa stone and marble, built during the reconstruction of the choir in 1717, the other two in tufa stone, decorate the sides of the choir, dedicated to the Virgin and the Sacred Heart.
Plouay was also the seat of the high justice of the Lordship of Pontkalleg, located in Berné. At the corner of the Place de l'Eglise and the Rue de Bécherel, admire the oldest house in the village, dating from 1594. To its right, under the Ancien Régime, stood the prison and the market hall; the latter housed a courtroom on the upper floor where judgments were handed down every Monday—market day. Punishments ranged from the pillory to imprisonment and, in the most serious cases, the death penalty. Executions took place just outside Plouay on a rise known as Lann Justice, the site of the Lordship’s justice pillars and gallows.
