The oldest part of Aschhausen castle in Schöntal was built in the 13th-14th centuries. In the early 16th century owner Hans Georg von Aschhausen supported the local robber baron, but in 1523 Swabian League sent army to destroy total of 23 this kind of camps of robber barons. Aschhausen castle was also destroyed.
Later it was restored and round tower was added in 1537. The current appearance dates from the 18th century.
The church of the former Franciscan monastery was built probably between 1515 and 1520. It is located in the UNESCO World Heritage Site of Old Rauma. The church stands by the small stream of Raumanjoki (Rauma river).
The exact age of the Church of the Holy Cross is unknown, but it was built to serve as the monastery church of the Rauma Franciscan Friary. The monastery had been established in the early 15th century and a wooden church was built on this location around the year 1420.
The Church of the Holy Cross served the monastery until 1538, when it was abandoned for a hundred years as the Franciscan friary was disbanded in the Swedish Reformation. The church was re-established as a Lutheran church in 1640, when the nearby Church of the Holy Trinity was destroyed by fire.
The choir of the two-aisle grey granite church features medieval murals and frescoes. The white steeple of the church was built in 1816 and has served as a landmark for seafarers.
