Masku in the context of "Nådendal Abbey"

Nådendal Abbey (Finnish: Naantalin luostari; Swedish: Nådendals kloster), was a Bridgettine abbey in then-Swedish Finland, in operation from 1438 to 1591. The abbey was first situated in Masku, secondly in Perniö (1441) and finally in Naantali in 1443. It was one of six monasteries in Finland during the Middle Ages, and, as a double monastery, the only one which accepted women.
