The church of Sastamala in Karkku (dedicated to St. Mary) was built in the end of 15th century. In the Middle Ages Karkku was the spiritual and administrative center for the northern Satakunta area. Unfortunately church was nearly abandoned for decades in the 19th and 20th centuries. During this time for example the floor was destroyed. The church was renovated in 1960-1977 and today it's used mainly for summer ceremonies.
There is a fine collection of historical artefacts in Sastamala church. Oldest items are probably a stone font from the 13th century and the part of gravestone with engraving "1304".
Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
