San Marcos Castle is a 12th-century fortress, commissioned by Alfonso X 'The Wise' upon the remains of a Moorish mosque on the banks of Guadalete River. Despite being so old (800 years), the castle is preserved in perfect conditions of use. Cultural events, conferences, lunches or dinners can be held both inside or outside in the garden, for up to 300 people.
The inside of the old mosque is an ideal place for events and closing dinners for conferences and conventions, because of its historic atmosphere. During the summer, the area around the fortress is an incomparable venue for celebrating open-air events.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.
