Crathes Castle is a 16th-century castle near Banchory in the Aberdeenshire region of Scotland. Construction of the current tower house of Crathes Castle was begun in 1553 but delayed several times during its construction due to political problems during the reign of Mary, Queen of Scots. It was completed in 1596 by Alexander Burnett of Leys, and an additional wing added in the 18th century.
This harled castle was built by the Burnetts of Leys and was held in that family for almost 400 years. The castle and grounds are owned and managed by the National Trust for Scotland and are open to the public.
The castle contains a significant collection of portraits, and intriguing original Scottish renaissance painted ceilings survive in several Jacobean rooms.
During 2004 excavations uncovered a series of pits believed to date from about 10,000 years ago. The find was only analysed in 2013 and is believed to be the world's oldest known lunar calendar. It is believed that it was used from 8,000 BC to about 4,000 BC. It is believed to pre-date by up to five thousand years previously known time-measuring monuments in Mesopotamia.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.
