At the beginning of the Kalmar Union age Sandemar was owned by the Teutonic Order of Livonia. Erik Axelsson Tott bought all the Order's property in Sweden in 1467. During the 1500s the ownership was unknown. In the 1600s the Sandemar belonged to families Oxenstierna, Bonde and Falkenberg. The Royal Council and president Gabriel Falkenberg completed the present main building around the year 1693. Sandemar is today privately owned by Karin Mattson Nordin, daughter of the real estate developer John Mattson.
The main building of Sandemar is made of wood, covered with tiles and the water side plates to protect against sea winds. The farm escaped the Russian ravages in 1719, probably through the deterrent effect of the nearby Dalarö Fortress had, and have therefore preserved the Carolinian period decorations. The English garden is added later with greenhouse, vegetable and fruit tree plantations.
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.
