With the number of 150 preserved tombstones stećci on Dugo Polje, it represents one of the biggest necropoli in general. The tombstones appear mostly in the form of slab, precisely 72 of them evidenced, then 59 crates, 14 tall crates and five gabled tombstones, four of which are with plinths.
The decorations found on total 32 tombstone stećci are mostly rosettes, appearing 34 times altogether. Most interesting decorations surely are the figural images. The three of those are especially unique and do not appear on any other stećak tombstones. The first one is found on the crate front, partially damaged today. There is an image of a man standing on the left of the surface. Another man stands to his right, with arms raised obliquely towards the head of the first. Behind him, stand two or three more men with their hands raised in the same manner. The meaning of this unconventional scene still remains unclear.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.
