St David's Hall (Welsh: Neuadd Dewi Sant) is a performing arts and conference venue in the heart of Cardiff, Wales.

Credit is given to the Conservative leader of Cardiff City Council, Ron Watkiss, for bringing St David's Hall to fruition.

[8] Architects Seymour Harris Partnership had the task of fitting a major 2000 seat, acoustically perfect auditorium, with surrounding dressing rooms, bars, foyers, a restaurant, offices and spacious concourse into a cramped city centre space.

The space available was so cramped that they had to fit the complex into and on top of an already planned and partly built St. David's Shopping Centre.

[11] The Wales Millennium Centre has added significantly to the arts and cultural scene already present in the city of Cardiff.

It re-branded the L3 Lounge venue, which has a partly seated capacity of 350 and is mainly used for daytime concerts, the Roots Unearthed folk series and Blas* – A Taste of the Fresh Welsh Sound.

[20] The cost of a replacement roof and wider refurbishment of the hall is estimated to be about £50 million and will be paid for by AMG as part of a conditional 45-year lease.

[27] Many organists travel to try out the organ, and others come to give recitals,[28] notably Olivier Latry,[26] Anne Marsden Thomas,[29] Ghislaine Reece-Trapp,[29] and Margaret Phillips.
