Roald Dahl Plass

Roald Dahl Plass is an open public square on the waterfront in Cardiff Bay, named for the Cardiff-born author. It sits among contemporary buildings, with the Wales Millennium Centre nearby and views across the bay. The plaza is a starting point for a waterside walk, and seasonal events can bring rides, a beach or festivals to the space. You can also explore nearby Mermaid Quay for places to eat and drink, or continue along the waterfront towards the dam.

A square by the water

Roald Dahl Plass is a public square in Cardiff Bay, named after the children’s author who spent his childhood and school years in Cardiff. The area was once a coal port; today, the plaza sits among modern buildings and cultural destinations.

The Wales Millennium Centre is close by, and the open space looks out towards Cardiff Bay. It works well as a pause on a waterfront walk or as a starting point for exploring the surrounding area.

Events and nearby stops

The plaza hosts events at different times of year. Summer programmes have included festivals, a temporary beach, a Ferris wheel and a circus, though activities vary. If you want more to do than walk around the square, check what is scheduled for your visit.

Mermaid Quay has restaurants and bars, with more places to eat in nearby side streets. Other stops within the surrounding area include the Norwegian Church, now a gallery, and the waterfront dam. Public toilets are not available in the plaza; use facilities in nearby public buildings or eateries.
