In the green corner of the docile Slavetić region with scattered orchards, vineyards and flower fields, on the top of the hill opposite the parish church of St Antony the Loner (Sv Antun Pustinjak) from 1600, lies the castle of the counts of Oršić. The old town is mentioned in 1294 within the foothill county, and after changing a few masters, in 1468 it came into possession of counts of Oršić, until 1869 when its owner became Levin Rauch. Originally built as a medieval castle with a Gothic centre and a guard tower and castle, in the subsequent renovations and annexes from the 16th to the 18th century this place was converted into a spacious castle. Construction phases are reflected through the Gothic, Renaissance and Baroque elements. This complex, comprised of several buildings for various purposes, closes shared inner courtyard. Above the entrance a year 1639 is indicated. In the castle there is a preserved kiln from the 17th century, a fireplace with consoles, and valuable portraits. Today the castle is privately owned.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.
