Dundee (Scottish Gaelic: Dùn Dèagh) is the fourth-largest city in Scotland. It is on the north bank of the River Tay's estuary which feeds into the North Sea. Dundee's history begins with the Picts in the Iron Age. During the Medieval Era, 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".
