 During the 1860s, when the Old College was under repair and the New College had yet to be built, both the Upper and Lower schools were housed in the building of Dulwich College Grammar School.In the summer of 1869 the upper school took possession of the current site, referred to as the New College, but it was not until Founder's Day (21 June) 1870 that the new college was officially opened by the Prince and Princess of Wales.The new college buildings, sited in the 60 acres of Dulwich Common, were designed in a hybrid of Palladian and Gothic styles in red brick and terracotta, by Charles Barry, Jr. (the eldest son of Sir Charles Barry).
