The Tate Modern art gallery was named Britain's best public building in 2001, the first ever winner of the Prime Minister's Better Public Building Award.
The former south London power station, converted into a national museum of modern art by Swiss architects Jacques Herzog and Pierre de Meuron, was selected from a shortlist of 10 buildings.

"The Tate Modern has set an exacting standard for the new award and shows how a well informed, clearly focused client can have the vision to produce a splendid building at excellent construction value"Sir Stuart Lipton, Chairman of CABE
