The Bridge of Dee or Brig o' Dee is a road bridge over the River Dee in Aberdeen, Scotland. The term is also used for the surrounding area of the city. Dating from 1527, the bridge crosses at what was once the City of Aberdeen's southern boundary. This was the site of a battle in 1639 between the Royalists under Viscount Aboyne and the Covenanters who were led by the Marquess of Montrose and Earl Marischal. This was the only substantial action of the First Bishops' War, ironically it took place after the peace treaty had already been signed.
The Bridge of Dee is approximately 32 feet above typical water height and consists of seven nearly semicircular ribbed arches, built using granite and Elgin sandstone. Today the bridge carries the main A90 road into Aberdeen from the south.
Previously listed as a Scheduled monument, it was de-scheduled on 16 February 2009 and designated a Category A listed structure.
