The old Benedictine monastery of Sant Miquel de Fluvià dates back to the second half of the 11th century. It consists of three naves with three semicircular apses. Its 12th century bell tower is a magnificent square tower with three storeys, separated by Lombard decoration.
Sant Miquel church and its bell tower were probably fortified in the 14th century and renovated later (in the 17th century). In 1974, a Roman kiln was found by chance about 100 m from the monastery. It was used to fire pottery and it is the only whole kiln in all of Catalonia.
