The National Assembly for Wales will be hosting a summer fun weekend with carnival games, arts and crafts and Welsh choirs on 27-29 August.
Coinciding with the Cardiff Harbour Festival there will also be face-painting, a soft play area and a special Senedd treasure hunt with prizes to be won.
The Senedd will be open every day from 10.30-16.30. Visitors can take a tour of this iconic building, including the debating chamber where the National Assembly for Wales sits; and take a well-earned rest while enjoying a hot drink and a Welsh cake at the Senedd coffee shop.
The Senedd steps are also an ideal place to watch the P1 Welsh Grand Prix of the Sea, which includes a fleet of eleven powerboats and more than 30 Jet Ski riders competing across the weekend.
