Skagen Old church, also called as 'Sand-Covered Church' was built in the 14th century and dedicated to Saint Lawrence of Rome. It was a brick church of considerable size and located 2 km south-west of the town centre. The white church tower is all that is visible of the former church, the rest of it demolished and the neighboring village having been buried under the sand from nearby dunes.
The church was named for the patron saint of sailors, but was buried by sand from Råbjerg Milen. The desertification that hit the area in the 18th century led to the abandonment of the old parish church to the migrating sands. This area of dunes threatened the church and the village for centuries, and the planting of trees could not prevent further encroachment: the church itself was demolished in 1775. All the furniture, fittings, and interior decoration were sold or moved to a new church (Skagen Church 1841), while the church tower being left to rise above the sand.References:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
