The Sheldonian Theatre in Oxford is the official graduation hall of the University of Oxford. It’s a Grade I listed building and was designed by Sir Christopher Wren prior to it’s building from 1664-1669. The theatre is named after Gilbert Sheldon who was Archbishop of Canterbury and chancellor of the University at the time and the primary financial backer of the project.
All the public ceremonies of the University are performed in the Sheldonian Theatre, notably the annual Encaenia. Encaenia is the ceremony at which the University of Oxford awards honorary degrees and also commemorates its benefactors.
