The earliest settlements date to around AD 700. Aalborg's position at the narrowest point on the Limfjord made it an important harbour during the Middle Ages, and later a large industrial centre. Architecturally, the city is known for its half-timbered mansions built by its prosperous merchants. Budolfi Church, now a cathedral, dates from the end of the 14th century and Aalborghus Castle, a royal residence, was built in 1550. Today, Aalborg is a city in transition from a working-class industrial area to a knowledge-based community. A major exporter of grain, cement, and spirits, its thriving business interests include Siemens Wind Power, Aalborg Industries, and Aalborg Portland. These companies have become global producers of wind turbine rotors, marine boilers and cement.
With its theatres, symphony orchestra, opera company, performance venues, and museums such as Aalborg Historical Museum and the Aalborg Museum of Modern Art, Aalborg is an important cultural hub. The Aalborg Carnival, held at the end of May, is one of the largest festivals in Scandinavia, attracting some 100,000 people annually.
