According the legend the first church in Selaön island was built by St. Olaf (Olaf II of Norway) in early 1000s. The current Ytterselö Church dates however from the 1100s. In the late Middle Ages it was changed as a square form hall church with vaults. The funeral chapel of Soop på Mälsåker family was added in 1650. The new choir was completed in 1728.
The beautifully carved triptych dates from c. 1500 and is made in Antwerpen. The crucifix was also made around 1500 and the pulpit around 1600. There is also an unusual tomb in the churchyard; The grave of Hans Åkesson Soop has four pillars and there is stone relief of Soop and his wife.References:
The Château du Haut-Koenigsbourg is situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years' War when it was abandoned. From 1900 to 1908 it was rebuilt at the behest of the German kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
The first records of a castle built by the Hohenstaufens date back to 1147. The fortress changed its name to Koenigsburg (royal castle) around 1157. The castle was handed over to the Tiersteins by the Habsburgs following its destruction in 1462. They rebuilt and enlarged it, installing a defensive system designed to withstand artillery fire.
The fortification work accomplished over the 15th century did not suffice to keep the Swedish artillery at bay during the Thirty Years War, and the defences were overrun.
