buildings at an-all girl college at Durham University have acquired names, 50 years after it moved to its present site.

Former principals of St Mary's were honoured as the current crop of undergraduates marked the golden jubilee of the Elvet Hill campus.

St Mary's, which began as a hostel for female students in Claypath in 1899, became a fully-fledged university college in 1920. It remains the only single sex college outside Oxford and Cambridge, with 700 members, 330 living on campus in the Elvet Hill halls of residence.

Former heads Irene Prowse (nee Calvert) and Joan Kenworthy joined current head Jenny Hobbs at a lunch ceremony to mark 50-years on-site.

To mark the jubilee 'the main building' at St Mary's will be known as the Fergusson Building, after former principal Margaret Fergusson (1940-55). The 'new building' has become the Williamson Building, after Ms Fergusson's successor Marjorie Williamson (1955-62). St Mary's conference hall becomes the Kenworthy Hall, after Ms Kenworthy (1977-99), the committee room is now the Calvert Room, after Irene Calvert (1974-77) and two seminar rooms will be named after Rachel Donaldson (1915-40) and Mary Holdsworth (1962-74).
