About
The Old House of Keys in Castletown preserves the former debating chamber of the House of Keys, the elected lower branch of Tynwald, the Manx parliament — one of the world's oldest continuous parliamentary bodies, with roots traced back to the Norse Thing assemblies of the Viking-age Kingdom of Mann and the Isles. This modest but historically weighty building served as the seat of Manx representative government until the House of Keys relocated to Douglas in the 19th century, and its preserved chamber offers a rare opportunity to stand in the actual room where generations of elected Manx representatives debated the island's laws and affairs.
Manx National Heritage has developed the site around an interactive recreation of a historic 19th-century parliamentary debate, allowing visitors to take on the roles of Members of the House of Keys and vote electronically on the real issues debated in the chamber during a specific historic sitting — an unusually immersive approach to constitutional history that brings the abstract business of 19th-century Manx politics to vivid, participatory life rather than presenting it through static display panels alone. The re-enactment situates visitors within genuine historical debates over Manx governance and reform, giving a hands-on sense of parliamentary process rarely offered at comparable heritage sites.
The House of Keys itself has a long and distinctive constitutional history: for centuries membership was effectively self-perpetuating, with the House co-opting new members as vacancies arose rather than submitting to popular election, a system that increasingly attracted criticism as 19th-century reform movements swept Britain and Ireland. The building preserved here witnessed the early stages of the campaign that eventually forced through a fully elected House of Keys in 1866, making Castletown's modest chamber the setting for constitutional arguments with lasting consequences for how the island is governed today. The Manx parliament's structure — the elected House of Keys sitting alongside an appointed Legislative Council, together forming Tynwald — took much of its recognisably modern shape in the decades following the debates the site's interactive exhibit recreates.
Situated within Castletown's historic quarter alongside Castle Rushen, the Old Grammar School, and the Nautical Museum, the Old House of Keys is one of the smaller Manx National Heritage sites in the town, with more limited opening than the castle itself, and rewards visitors with a specific interest in constitutional and political history or in the Tynwald's status as one of the world's oldest parliaments, a claim explored in more depth at the Manx Museum in Douglas.

💡 Visitor Tips
- Check opening days before visiting — this is one of the smaller Manx National Heritage sites with more limited hours than Castle Rushen or Peel Castle.
- Try the interactive voting recreation — it's the standout feature of the site and gives a genuinely different way of engaging with 19th-century political history compared to reading display panels.
- Combine your visit with Castle Rushen, the Old Grammar School, and the Nautical Museum, all within a few minutes' walk in Castletown's historic quarter.
- This is a short visit — allow 20 to 35 minutes, particularly if you take part in the full interactive debate experience.
- Children under 18 enter free, and the interactive voting exhibit tends to appeal particularly to older children and teenagers interested in how democracy works.
- If visiting several Manx National Heritage sites during your stay, the Heritage Pass offers better value than paying for individual admissions.
Highlights
The Historic Debating Chamber
The preserved chamber of the House of Keys is the physical heart of the site, the actual room in which elected members of the Manx parliament's lower branch debated the island's laws before the House relocated to Douglas in the 19th century. Standing in the chamber gives a direct, tangible connection to the practical workings of one of the world's oldest continuous parliamentary traditions, a claim more fully explored through the Tynwald displays at the Manx Museum in Douglas.
Interactive Recreation of a Historic Debate
Manx National Heritage's interactive exhibit invites visitors to take on the roles of 19th-century Members of the House of Keys and vote electronically on real historical issues debated in the chamber, using an audio-visual recreation of the period's parliamentary procedure and rhetoric. This hands-on approach to constitutional history is one of the more distinctive interpretive experiences on the island, turning what could be a dry procedural subject into an engaging, participatory exercise in understanding 19th-century Manx politics and reform debates.
Tynwald and the World's Oldest Parliament
The site situates the House of Keys within the wider story of Tynwald, the Manx parliament whose origins are traced to Norse-age Thing assemblies and which claims continuous operation since at least AD 979, making it one of the oldest parliamentary institutions in the world still functioning today. Interpretation explains how the bicameral structure of Tynwald — combining the elected House of Keys with the Legislative Council — developed over the centuries into the system that still governs the island.
19th-Century Manx Political Reform
The specific historical debates recreated for visitors touch on genuine 19th-century reform issues facing the House of Keys, a period when questions of representation, electoral reform, and the House's relationship with the Lieutenant Governor and Legislative Council were actively contested — offering insight into a lesser-known but constitutionally significant period of Manx political history.
Collections
The Old House of Keys' primary heritage asset is the preserved debating chamber itself, the historic seat of the elected House of Keys before its relocation to Douglas in the 19th century. Rather than a conventional object-based collection, the site's main interpretive feature is an interactive audio-visual recreation allowing visitors to participate in a historic 19th-century parliamentary debate and vote electronically as a Member of the House of Keys.
Supporting interpretation explains the wider history and constitutional significance of Tynwald, the Manx parliament, situating the chamber within the island's claim to one of the world's oldest continuously functioning parliamentary traditions.
