Venue: New Cardiff Bay Arena
Town: Cardiff, GB

New Cardiff Bay Arena, also referred to as Atlantic Wharf Arena, is an indoor arena under construction in Atlantic Wharf, a southern area of the city of Cardiff, Wales. The multi-purpose 16,500-capacity arena is being built on a site near to Cardiff Bay's Wales Millennium Centre (WMC) and is expected to open in 2028. It forms part of a wider masterplan to regenerate the city's wharf area with a large mixed-use development. After a number of delays, construction began following the groundbreaking ceremony in September 2025 and is expected to be undertaken in four phases over multiple years: the first being the construction of the new arena, WMC's digital and "immersive" arts theatre, a replacement hotel and multi-storey car park followed by the relocation of the Red Dragon Centre's tenants into a new complex. The third phase of the masterplan would include a new office space delivered along with an additional hotel and finally new homes and apartments, with potential for more commercial space; the latter neighbourhood phase is dependent on proposed plans being approved to replace Cardiff Council's ageing County Hall with a new smaller purpose-built building. Currently the city lacks a large multi-purpose indoor arena suitable for hosting a number of major sporting and music events, such as concerts, the BBC Sports Personality of the Year and the Gymnastics World Championships, with a capacity of 10-15,000 to bridge the significant gap between that of the CIA and the Millennium Stadium, where the majority of large-scale events are hosted. In November 2018, it was reported that a 15,000-seat indoor arena would be built on the site of the Red Dragon Centre, a large entertainment and leisure complex in the south of the city. The Atlantic Wharf site was chosen by the council as the preferred option over six other potential sites, including Callaghan Square near Cardiff Central railway station, the 5,000-seat Cardiff International Arena (CIA), with an arena also suggested
