The Besleti Bridge, also known as the Queen Tamar Bridge, is a medieval arched stone bridge at Sukhumi, Georgia’s breakaway republic of Abkhazia. It dates back to the late 12th century. Thirty-five meters in overall length and eight meters high, this single-arch bridge is one of the most illustrative examples of the medieval bridge design popular during the reign of Tamar of Georgia (r. 1184-1213) who is traditionally credited to have commissioned the construction of the Beslet bridge.
In the vicinity of the bridge are the ruins of medieval combat towers, a testimony to strategic importance of the locale.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.
