The square was developed by master builder Thomas Cubitt in the 1820s, as one of a pair with Tavistock Square, which is a block away and has the same dimensions. As with most London squares the central garden was originally for the private use of the residents of the surrounding houses, but it now belongs to the University of London and is open to the public. The square is named after the second wife of the 6th Duke of Bedford, Lady Georgiana Gordon, daughter of Alexander Gordon, 4th Duke of Gordon. The university owns many of the buildings in the square and in early 2005 it submitted an application for a refurbishment of the square, including the reinstatement of railings similar to the originals. The work was completed in 2007. The west side of the square is dominated by the listed church of Christ the King and next to it the home of Dr Williams's Library.
Nos. 16–26, on the western side of the square, were not completed until 1855, and they represent some of the last buildings created by Thomas Cubitt. They now mostly house UCL academic departments. For example, No. 22 houses the Department of Science and Technology Studies.
Passfield Hall, a halls of residence for undergraduates at the London School of Economics, is on the north side of the square.[1]
