The Masku Church, built probably in 1490-1510, and surroundings represents one of the oldest parishes in Western Finland. The Masku parish was mentioned first time in 1234. The Mural paintings and pulpit date from the 17th century. There are also several medieval artefacts like crucifix and Silesian altarpiece located inside the church. Near the church is also "Humikkalan kalmisto", an Iron Age burial ground.
Finnish National Board of Antiquities has described the church area as national built heritage.
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.
