Dundee (Scottish Gaelic: Dùn Dèagh) is the fourth-largest city in Scotland with a population of around 150,000 people. It is situated on the north bank of the Firth of Tay on the east coast of the Central Lowlands of Scotland. The Dundee area has been settled since the Mesolithic with evidence of Pictish habitation beginning in the Iron Age. During the Medieval Era the city became a prominent trading port and 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 prominence due to its marmalade industry and its journalism, giving Dundee its epithet as the city of "jute, jam and journalism".
