Tŷ Hywel

Tŷ Hywel is a government office building with six floors in Cardiff Bay, Wales, connected to the Senedd building through two covered link bridges. The two structures work together as a single administrative center for the Welsh legislature.

The building first opened in 1993 as Crickhowell House and served as a temporary meeting space for the National Assembly of Wales until 2006. After the legislature moved to the new Senedd building, it was converted for administrative and office functions.

The name honors Hywel Dda, a medieval Welsh king whose legal reforms shaped the foundations of Welsh governance. Visitors walking through the building encounter this historical connection woven into its identity.

The building is located at Bute Place in Cardiff Bay and is easily accessible by public transportation. Visitors should note that some areas may have restricted access since it continues to function as an active administrative center.

The building houses Siambr Hywel, a debating chamber designed for young people that functions as a learning center for civic engagement. This special space allows students to gain debate experience within an actual parliamentary setting.
