The Radcliffe Observatory Quarter (ROQ) is a major University of Oxford development project in Oxford, England, in the estate of the old Radcliffe Infirmary hospital. The site, covering 10 acres is in central north Oxford. It is bounded by Observatory Street and Green Templeton College to the north, the Woodstock Road to the east, Somerville College to the south, and Walton Street to the west. The project and the new university area is named after the grade I listed Radcliffe Observatory to the north east of the site, now the centrepiece of Green Templeton College, which is intended to form the visual centrepiece of the project.
