 The main buildings are located in the centre of Oxford , between Turl Street , Ship Street , Cornmarket Street and Market Street . The main entrance is on Turl Street . The buildings are arranged in three quadrangles , the first quadrangle containing the oldest college buildings and the third quadrangle the newest . The foundation charter gave to the college a site between Market Street and Ship Street ( which is still occupied by the college ) as well as the buildings of a defunct university academic hall on the site , called White Hall . The buildings that now surround the first quadrangle were erected in stages between 1571 and the 1620s ; the principal 's lodgings were the last to be built . Progress was slow because the new college lacked the " generous endowments " that earlier colleges enjoyed . Before new buildings were completed , the students lived in the old buildings of White Hall .
