Tynwald, meaning the assembly field, is an institution unique to the Isle of Man and is the successor of the Norse meeting of freemen. It meets on Tynwald Day, 5 July, on Tynwald Hill and is attended by the president of Tynwald, the lieutenant-governor, the bishop, the deemsters, the Legislative Council, and the House of Keys. Its main task is to ratify or approve laws and to appoint boards which serve as administrative committees. The Tynwald shares with the Icelandic Althing the claim to be the oldest surviving parliamentary institution.
