Princes Square is a shopping centre on Buchanan Street in central Glasgow, Scotland. It was first designed and built in the 1840s by John Baird and other architects. It was developed in 1988 to a design by Edinburgh architects, the Hugh Martin Partnership. The new five-storey, 10,450-square-metre (112,500 sq ft) retail centre occupies a pre-existing cobbled Princes square dating from 1841, which was reconfigured by enclosing the entire space below a new clear glass domed and vaulted roof. An expansion was completed in summer 1999, extending the centre into Springfield Court and providing a further 1,860 square metres (20,000 sq ft) of retail area and a new retail frontage to Queen Street.
