The Radcliffe Observatory is at the heart of the College site. On the ground floor is the College dining room and the Grzeslo Dning Room, and on the first floor the Common Room for College members with a selection of newspapers and other periodicals. On this floor there is also the Fellows' Room and the Wiiliam Gibson Room, a small provate dining room for up to 14 people.
The Common Room is also used for music recitals and for hosting small academic events, including workshops and seminars.
The former observing room on the top floor (to which access is limited) offers a magnificent view of Oxford and the development of the University's Radcliffe Observatory Quarter next door to the College.
