Lonely Planet review
The centrepiece and symbol of Cardiff Bay's regeneration is the superb Wales Millennium Centre, an architectural masterpiece of stacked Welsh slate in shades of purple, green and grey topped with an overarching bronzed steel shell. Designed by Welsh architect Jonathan Adams, it opened in 2004 as Wales' premier arts complex, housing major cultural organisations such as the Welsh National Opera, National Dance Company, National Orchestra, Literature Wales, HiJinx Theatre and Ty Cerdd (Music Centre of Wales).
The roof above the main entrance is pierced by 2m-high letter-shaped windows, spectacularly backlit at night, that spell out phrases from poet Gwyneth Lewis: 'Creu Gwir fel Gwydr o Ffwrnais Awen' (Creating truth like glass from inspiration's furnace) and 'In these stones horizons sing'.
You can wander through the large public lobby at will; the Cardiff Bay tourist information centre is here and there's a stage which is often used for free performances. Guided tours lead visitors behind the giant letters, onto the main stage and into the dressing rooms, depending on what shows are on.
