Dundee (Scottish Gaelic: Dùn Dèagh)is the fourth-largest city in Scotland. It is on the north bank of the River Tay's estuary and is near the east coast and the North Sea. Dundee's history begins with the Picts in the Iron Age. During the mediaeval period, it was the site of many battles. Throughout the Industrial Revolution, the local jute industry caused the city to grow rapidly. In this period, Dundee also gained a reputation for its marmalade industry and its journalism, giving Dundee its epithet as the city of "jute, jam and journalism". Dundee's population is 143,090. However, if contiguous settlements—such as Monifieth, Birkhill, and Invergowrie—are counted, the number is around 170,000. Dundee's population reached a peak of nearly 200,000 at the start of the 1970s. It has since declined, due to outward migration and the council boundary changes of the 1970s and 1980s, which saw Dundee lose suburbs to the surrounding counties. Today, Dundee is known as the City of Discovery, in honour of Dundee's history of scientific activities and of the RRS Discovery, Robert Falcon Scott's Antarctic exploration vessel, which was built in Dundee and is now berthed there. Biomedical and technological industries have grown since the 1980s. The city now accounts for 10% of the United Kingdom's digital-entertainment industry. Dundee has two universities—the University of Dundee and the University of Abertay Dundee. The city is home to the Scottish Dance Theatre, which is based in the city's Dundee Repertory Theatre. The Royal Scottish National Orchestra regularly plays in the city's Caird Hall. On 5 March 2004 Dundee was granted Fairtrade City status.
