Aberdeen

Aberdeen needs 1 day: walking Union Street and the historic Old Aberdeen quarter, with entire buildings built of grey granite that sparkles in sunlight due to its mica content, is the main reason to visit. April-September is best. It's mid-priced by British standards. It's Scotland's third most populous city, nicknamed «the Granite City» for its distinctive architecture, and the unofficial capital of the North Sea oil industry since the 1970s.
