Aberdeen is Scotland’s third largest city and nicknamed “The Granite City.” It is built on a ridge that runs east-west between the Rivers Dee and Don. The main commercial street, Union Street, follows the line of the ridge. Here you can watch large ships sailing through the narrow navigation channel, and explore the delightful little district of Footdee with its picturesque 19th century fishers’ cottages. The Maritime Museum is situated in Aberdeen’s oldest building and overlooks the harbor. It presents a comprehensive overview of the city’s seafaring and shipbuilding past. Another of the town’s attractions is Provost Skene’s House, a noble 16th century mansion. The Abderdeen Art Gallery houses works by young contemporary painters as well as more traditional works including an excellent Victorian Scottish section, with many canvases by William Dyce. There is also a Rodin bronze statue and an extensive selection of watercolors and etchings, including a handful of Picassos and Chagalls. Old Aberdeen is a district with stone mansions lining leafy lanes, and most of the buildings belong to the university. At its heart is the imposing 15th century St. Machar’s Cathedral, one of the country’s few examples of a fortified cathedral.
