Dunnottar Castle could be called a hidden gem amongst the plethora of Scottish castles . It is not very well-known but it has a fascinating history including visits from William Wallace and Mary, Queen of Scots.The castle must have the most spectacular location in Scotland , sitting on a rocky promontory on the east coast of Scotland just outside Stonehaven , about 15 miles from Aberdeen . The word impregnable was probably invented for this castle. It is surrounded on all sides by a sheer cliff . Entry is by a tunnel through the cliff . Once you actually reach the top the views are stunning. In the 12th Century Dunnottar Castle became a Catholic settlement with the first stone chapel being consecrated in 1276. According to “Blind Harry”, a 15th Century poet, whose epic poem was an inspiration for the 1996 film “Braveheart”, William Wallace set fire to this chapel with a garrison of English soldiers taking refuge inside. The current chapel was built in the 16th Century.Dunnottar Castle was home to one of the most powerful families in Scotland, the Earls Marischal, from the 14th century when Sir William Keith, the 1st Earl Marischal, built his Tower House, also known as the Keep. The Earl Marischal was an office bestowed on the Keiths by James II. The role was one of the three great offices of State, along with the Constable and the Steward. The Earl Marischal had specific responsibility for ceremonial events, the Honours of Scotland and for the safety of the King’s person within parliament. Consequently it was not unusual for the monarchy, including Mary Queen of Scots, to spend time and stay at Dunnottar.Nowadays you can get married in Dunnottar castle , although you do so at your own risk since there is no shelter in the castle buildings .
