The Whitworth Art Gallery is an art museum in Manchester, England, containing about 55,000 items in its collection. The museum is located in Whitworth Park south of the Oxford Road campus of the University of Manchester. Since 2006, the director of the gallery is Dr Maria Balshaw.
The extension, which opened on 14 February 2015 doubles the gallery's public space. It will provide more space for displaying the 55,000 items in the gallery's collection and link the building to Whitworth Park.
The refurbishment and extension work resulted in the development winning a RIBA National Award in 2015 and subsequently being shortlisted for the RIBA Stirling Prize. The Whitworth won the Museum of the Year award in 2015.
