Douglas City Hall, Isle of Man

Tynwald (Manx: Tinvaal), or more formally, the High Court of Tynwald (Manx: Ard-whaiyl Tinvaal) or Tynwald Court, is the legislature of the Isle of Man. It consists of two chambers, known as the branches of Tynwald: the directly elected House of Keys and the indirectly chosen Legislative Council. When the two chambers sit together, they become "Tynwald Court". The chambers sit jointly, on Tynwald Day at St John's for largely ceremonial purposes, and usually once a month in the Legislative Buildings in Douglas. Otherwise, the two chambers sit separately, with the House of Keys originating most legislation, and the Legislative Council acting as a revising chamber.

The House of Keys (Manx: Yn Kiare as Feed) is the directly elected lower house of Tynwald, the parliament of the Isle of Man, the other branch being the Legislative Council.

The Legislative Council (Manx: Yn Choonceil Slattyssagh) is the upper chamber of Tynwald, the legislature of the Isle of Man. The abbreviation "LegCo" is often used.It consists of eleven members (MLCs): Eight members elected by the House of Keys Three ex officio members: President of Tynwald, ex officio President of the Legislative Council (casting vote) Bishop of Sodor and Man Attorney General for the Isle of Man (non-voting)Historically, most or all elected MLCs were former MHKs, but this practice has now much reduced or ceased. Formerly, the Lieutenant Governor presided over the Legislative Council and over Tynwald Court (a joint session of the Council and the House of Keys). Now, however, the President of Tynwald, who is chosen by the whole Tynwald for a five-year term, is the ex officio President of the Legislative Council, and presides over both the Legislative Council and Tynwald Court, except that the Lieutenant Governor presides once a year on Tynwald Day. Furthermore, the Church of England Bishop of Sodor and Man and the Attorney General have seats on the Legislative Council. The Bishop is a voting member, the Attorney General is a non-voting member, and the President has the casting vote. The Council does not usually originate legislation; most of the time, it reviews draft legislation originating in the House of Keys. However, it is possible for legislation to originate in the Council: a recent example is the Equality Act 2017.

Douglas (Manx: Doolish, pronounced [ˈdðuːlʲəʃ]) is the capital city and largest settlement of the Isle of Man, with a population of 26,677 (2021). It is located at the mouth of the River Douglas, and on a sweeping bay of two miles (three kilometres). The River Douglas forms part of the city'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 (actually located in nearby Onchan), and finally the seat of the legislature, Tynwald, to Douglas from the ancient capital, Castletown. The city is the island's main hub for business, finance, legal services, shipping, transport, shopping, and entertainment. The annual Isle of Man TT motorcycle races start and finish in Douglas.
