The Cardiff Bay Barrage is 1.1km long and extends from Cardiff docks in the north to Penarth in the south. This major civil engineering construction project created the Bay, which has over 13km of waterfront. The £220m project was the catalyst for the £2 billion regeneration of the old docklands areas of Cardiff and Penarth.

Staffed 24 hours a day, 365 days a year, the Barrage Control room is not normally open to the public.

Always wanted to know how Cardiff Bay Barrage operates? Cardiff Harbour Authority is hosting free tours of the Control Room and Barrage in September.

The Barrage Lock Keepers, who are responsible for operating and maintaining the Barrage, and undertaking essential procedures, including the operation of the sluice gates to control the level of water in the Bay, will be conducting tours of Barrage Control and the Barrage.

The tour will last approximately 2 hours. Please be aware that there is a steep, narrow staircase leading up to the Control Room with no lift access. This event isn't suitable for children.

There are 12 spaces available per tour. Tour places must be booked in advance, either online at or by calling 029 2087 7900.
