Cardiff Bay Visitor Centre (known informally as "the Tube") was a piece of modern architecture designed by the architect Will Alsop for Cardiff Bay, Wales, in 1990. It was finally dismantled in 2010. A panel of architectural experts has said the building "single-handedly put Cardiff on the architectural map". [3]
Architect Will Alsop was already involved in the development of the Cardiff Bay Barrage when asked, by the Cardiff Bay Development Corporation (CBDC), to design a visitors' centre. The building was completed during the Summer of 1990, [4] located close to the Victorian Pierhead Building. [1] It cost somewhere between £350,000 [4] and £500,000 [5] and was originally expected to last for only two years, the duration of its first temporary planning consent. [1] [5]
The building was in the shape of a long flattened tube, glazed at each end. Alsop liked to compare its shape to a disposable cigarette lighter. [4] It was constructed using a series of oval steel ribs, clad with marine plywood and covered with external skin of nylon-pvc fabric. [4] [6] It was one of the first significant projects completed by Neil Thomas's structural engineering consultancy, Atelier 1.
Ripple-like slots were cut into the plywood, allowing dappled daylight into the interior. [1] It was shortlisted for the Royal Institute of British Architects (RIBA) Building of the Year award (forerunner of the Stirling Prize). [4]
The visitor centre was built to house an exhibition about the new Cardiff Bay development. [4] In 1993 the building needed to be moved from its location east of the Pierhead Building. Rather than permanently dismantle it, the structure was put on the back of a 50m long Mammoet self-propelled transporter and moved to another part of the Bay. [4] At the same time a new entrance ramp was added on the north side and steel brackets fixed to the end ribs to allow the pvc-nylon sheath to be fully stressed along the building's length. It continued to house interactive exhibitions and a scale model of Cardiff. [7]
Because of its distinctive shape, the visitor centre became known locally as 'The Tube'. [5] [7] In 2009 it was listed ninth in the Top Ten free attractions in Wales. [8]
Cardiff Bay Visitor Centre was listed by a panel of experts as one of the Top 50 Buildings of the 1990s, saying the building had "single-handedly put Cardiff on the architectural map". [3]
 
 In 2006 the building's operators, Cardiff Initiative, ceased trading and The Tube closed for several weeks, reopening under the management of Cardiff Council. [7]
The Tube was finally dismantled (and put into storage) in Autumn 2010 to make way for a new link road. [5] "I'm surprised it's lasted this long," said Alsop's practice partner John Lyall. [5]
