Tŷ Hywel

Tŷ Hywel is a building in Cardiff, Wales, used by Senedd Cymru (the Welsh Parliament). It is named after the medieval king Hywel Dda[1] and was previously known as Crickhowell House (Welsh: Tŷ Crughywel), after the former Secretary of State for Wales, Lord Crickhowell.[2][3] It houses Members of the Senedd and their staff, as well as staff of the Senedd Commission. The Welsh Government also operates from the building and occupies one whole floor and part of another. It is leased by the Senedd under the Government of Wales Act 1998.[2]

Tŷ Hywel

The building was opened in 1991 and has a total floor area of 11,583 m2 (124,680 sq ft). It is built of red brick and is connected to the Senedd debating chamber in Cardiff Bay. Crickhowell House was used as a temporary debating chamber for the National Assembly for Wales from 1999 until its new building, also originally known as the Senedd, was opened in 2006. On 25 June 2008 the Prince of Wales officially opened Siambr Hywel, the National Assembly's youth debating chamber and education centre, based in the former debating chamber in Tŷ Hywel.[4]
