... and you climb to the top you will be graced with views like this.
Dumbarton Castle has been around in one form or another since the Iron Age. It is the oldest known stronghold in Britain, due to it's location atop a large rock of volcanic basalt. Some of the well-known historical figures to have visited the castle include Merlin (Yeah, that Merlin. From King Arthur and the knights of the Round Table), King Olaf the Viking, Alexander II, David II, James IV, James V, Mary Queen of Scots (whose possessions can be found at just about every known historical site), and maybe even William Wallace (AKA Braveheart) whose betrayer John de Menteith was governor of the castle.
All in all, it's a rather awesome place to visit and learn even more about the fascinating history of country we're residing in. Not to mention the views are spectacular on a sunny day. Be prepared to climb the narrow stairs to the top though!
