Douglas is the capital and largest town of the Isle of Man, with a population of 26,677. It is located at the mouth of the River Douglas, and on 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 it grew rapidly as a result of links with the English port of Liverpool in the 18th century. Further population growth came in the following century, resulting during the 1860s in a staged transfer of the High Courts, the Lieutenant Governor's residence, and finally the seat of the legislature, Tynwald, to Douglas from the ancient capital, Castletown.
