[1] The Stirling Prize is presented to "the architects of the building that has made the greatest contribution to the evolution of architecture in the past year".
These awards are given to buildings showing "high architectural standards and substantial contribution to the local environment".
In addition to the RIBA Stirling Prize, five other awards are given to buildings on the long-list.
In 2000 several architects from Scotland and Wales made claims of metropolitan bias after five out of seven designs shortlisted by judges were located within London.
The chairman of the judges in the contest rejected the claims, saying that the first Stirling Prize was awarded to a building in Salford, Greater Manchester.
