The village of Guillac has a church dedicated to Saint-Seurin (Bishop of Bordeaux in the XNUMXth century).
Of Romanesque foundation, it was a former priory which belonged to the abbey of Sauve-Majeure (of which mention is made at the end of the XNUMXth century). A statue of the Virgin, dating from the XNUMXth century, is above the portal, in a shell-shaped niche.
At the foot of the church is a remarkable cemetery cross, also dating back to the XNUMXth century, which has a fluted twisted column shaft.
The Lyssandre stream has its source in the town. It flows a few kilometers further into the Dordogne at Branne.
