The ClockTower at 22 Princes Street in the Auckland CBD is the University of Auckland's most recognisable building, a 54-metre tower faced with Mount Somers stone. It was built as the Old Arts building, and it was designed by R.A. Lippincott, a Chicago-trained architect and brother-in-law of Walter Burley Griffin, who designed Canberra. The tower was inspired by Tom Tower at Christ Church, Oxford, and it has come to stand for the university. Inside, the octagonal hall is vaulted and galleried, with a mosaic floor and piers. For many years the building housed the Arts, Architecture, Law and Music departments, the library and the University Hall. Between 1985 and 1988 the main wing was renovated and cleaned, which brought back the white finish that gave it the nickname "the wedding cake". The renovation won an award from the Institute of Architects. The site describes the building's history, so the story of the place is the main draw for a visitor.
