University College, informally known as Castle, is a college of Durham University in Durham, England. Centred on Durham Castle on Palace Green, it was founded in 1832 and is the oldest of Durham's colleges. As a constituent college of Durham University, it is listed as a higher education institution under section 216 of the Education Reform Act 1988. Almost all academic activities, such as research and tutoring, occur at a university level.
University College moved into its current location in 1837. Around 150 students are accommodated within Durham Castle. Other college buildings, including converted 18th century houses and purpose-built accommodation from the 1950s, 1970s and 1980s, are within five minutes' walk of the castle. The college has 700 undergraduates and is currently the most over-subscribed college of the university. In 1987 it admitted women undergraduates for the first time, having previously had an all-male student body.
