Douglas is the capital and largest town of the Isle of Man, with a population of 28,939 people (2011). It is located at the mouth of the River Douglas, and a sweeping bay of two miles. The River Douglas forms part of the town's harbour and main commercial port.
Douglas was a small settlement until rapid growth occurred as a result of links with the English port of Liverpool in the 18th century. Further population growth came as the town industrialised in the following century, resulting in 1869 with the island's government, the Tynwald, relocating to Douglas from Castletown. The island's High Courts are also based in the capital.
The town serves as the Island's main hub for business, finance, legal services, shipping, transport, shopping, and entertainment. The annual Isle of Man TT in motorcycle racing starts and finishes in Douglas.
