During the 13th century Dardagny Castle, along with Bruel, La Corbière and Malval, formed a ring of castles, which secured the western boundary of the lands of the Bishop of Geneva. In 1298 there were two castles, which were separated by a small road. Each one belonged to one of the two noble families in Dardagny. In the 14th century, the south building was over two stories high and had a tower.
In 1646, the Favre family inherited both feudal domains in the village. Daniel Favre joined the two castles in 1655 through a gallery. He also built three towers and expanded the entire building. In 1721 Dardagny Castle went to Jean Vasserot who had the courtyard roofed over and converted into a feast hall which was decorated with Italian paintings. In 1740 staircase was built in the small central tower and the received its present appearance. It was purchased in 1904 by the municipality. They restored it in 1926 and 1932, after initially considering demolishing the building. Since then, the building has housed local government and a school.
References: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.
