The Old House of Keys (Manx: Shenn-thie y Chiare as Feed) is the former meeting place of the House of Keys, the lower house of Tynwald, the Isle of Man's parliament. It is located across the street from Castle Rushen in Castletown, the former capital of the Isle of Man, in the south of the island. The building was used as the House of Keys from 1821 until 1874, when the parliament was moved to Douglas. Prior to 1821, the House of Keys had no official home, but met first at Castle Rushen, and later at the Bishop of Sodor and Man's library in Castletown. After criticism from a Royal Commission, plans were drawn up for a new meeting house for the Keys in 1813, but after concerns about the cost, they were redrawn and approved in 1819. The building, designed by Thomas Brine, was completed in 1821. It housed the House of Keys until 1874, when the Keys followed the other primary functions of the island and moved to Douglas. After their move, the Old House became a branch of Dumbell's Bank, and later Parr's Bank. In 2000, Manx National Heritage acquired the building and began restoring the house to how it appeared in 1866. The building opened to the public as a museum in November 2001.
