The area's main city is Aberdeen, known the world over as the Granite City for the distinctive grey stone of its buildings; it is also Scotland’s third city.

Angus is an ancient administrative area, it was also known as Forfarshire before 1928, and occupies land to the north of the Tay Estuary. Its county town was Forfar, although Dundee was its largest town. Agriculture and fishing were its major industries in the rural areas. Dundee owed its development in the mid-19th Century to jute shipped from the Indian sub-continent. This was spun and converted into sacking, horse blankets, sails and other canvas goods. This resulted in Dundee being referred to as "Juteopolis".
Shipbuilding was also a major industry, its most famous ship being RRS Discovery for Captain Scott's Antarctic expedition. Other towns in its boundary include Kirriemuir, Montrose and Arbroath; where the Declaration of Independence was signed in 1320.

Sutherland is one of the largest, yet most sparsely populated, counties in Scotland. It was under Norse rule until the 12th Century when it was claimed over to Scotland by William The Lion. Dornoch is its largest town, although Golspie was its County Town until it became part of the Highland Region.
The county is closely associated with the infamous Highland Clearances largely because of the actions of Patrick Sellar, factor to Elizabeth, Countess of Sutherland. Dunrobin, the fortress home of the Dukes of Sutherland, is on the outskirts of Golspie.
