Union Street
Aberdeen's grand main street, a mile of granite from the Castlegate to Holburn Junction, carried over the Denburn valley on a single great arch.
Union Street is the spine of Aberdeen, a straight, wide street of silver-grey granite that runs for about a mile from the old Castlegate to Holburn Junction.
Aberdonians call it the Granite Mile.
It was a bold idea. At the end of the 1700s the roads into the town were narrow, twisting and steep, and the council decided to cut a grand new street straight west across the hills and valleys. Houses were bought and pulled down, a hill was levelled, and the Denburn valley was crossed by the Union Bridge, a single granite arch of 130 feet designed by Thomas Fletcher. It opened the growing city up to the west.
Walk it from end to end and you pass the Town House and the Mercat Cross, the arches of the Kirk of St Nicholas, the bridge over Union Terrace Gardens and grand granite banks and halls. It is at its best in low evening light, when the granite catches the sun.

A city street, there at any time.
