Mormaer of Angus, is recorded in the Chronicle of the Kings of Alba as having died at the Battle of Brunanburh. Angus is marketed as the birthplace of Scotland. The signing of the Declaration of Arbroath at Arbroath Abbey in 1320 marked Scotland's establishment as an independent nation. It is an area of rich history from Pictish times onwards. Notable historic sites in addition to Arbroath Abbey include Glamis Castle, Arbroath Signal Tower museum and the Bell Rock Light House. Geography Angus can be split into three geographic areas. To the north and west, the topography is mountainous. This is the area of the Grampian Mountains, Mounth hills and Five Glens of Angus, which is sparsely populated and where the main industry is hill farming. Glas Maol – the highest point in Angus at 1,068 m (3,504 ft) – can be found here, on the tripoint boundary with Perthshire and Aberdeenshire. To the south and east the topography consists of rolling hills (such as the Sidlaws) bordering the sea; this area is well populated, with the larger towns. In between lies Strathmore (the Great Valley), which is a fertile agricultural area noted for the growing of potatoes, soft fruit and the raising of Aberdeen Angus cattle. Montrose in the north east of the county is notable for its tidal basin and wildlife. Angus's coast is fairly regular, the most prominent features being the headlands of Scurdie Ness and Buddon Ness. The main bodies of water in the county are Loch Lee, Loch Brandy, Carlochy, Loch Wharral, Den of Ogil Reservoir, Loch of Forfar, Loch Fithie, Rescobie Loch, Balgavies Loch, Crombie Reservoir, Monikie Reservoirs, Long Loch, Lundie Loch, Loch of Kinnordy, Loch of Lintrathen, Backwater Reservoir, Auchintaple Loch, Loch Shandra, and Loch Esk.
