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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
