Nousiainen Church

The church of Masku is a medieval stone church probably built between 1490 and 1510, dedicated to John the Baptist and St. Ursula. Next to the church is the Masku Museum, founded in 1974, which collects art objects from the local peasantry.

The church of Lemu is a medieval stone church dedicated to St. Olaf. It was probably built between 1460 and 1480. The present neoclassical wooden bell tower of the church, dating from 1812, is located on the north-eastern side of the church. The old bell tower, built in the 1570s, had fallen into ruin at the turn of the 18th century when plans for the present bell tower began to be drawn up. Next to the Lemu church is the homeland museum called Kemppien tupa. The museum is housed in a former parish warehouse built in 1858.

Mynämäki Church, originally called St. Laurus Catholic Church, is the second-largest medieval stone church in Finland. The church's sacristy is the oldest part of the building and some date its construction to the 13th century, while others date it from 1425 to 1440.
