Heritage Open Day: An opportunity to look inside one of the remaining Oxford college barges. An opportunity to visit a special part of Oxford’s floating history. The college barges, unique to Oxford, preexisted the current boathouses and were used for spectating and celebrating the rowing as well as for changing rooms and club houses. The Corpus Christi college barge is a unique example of Edwardian architecture, and one of the only surviving examples of its ilk.
