Pembroke College, founded in 1347, is one of Cambridge's older colleges and has a pleasant character quite different from the grander Trinity or St John's — more intimate, less overrun with visitors. The college chapel, designed by Christopher Wren in 1663, was Wren's first completed architectural work and is a beautiful, restrained piece of early English Baroque, quite unlike the Gothic chapels that dominate elsewhere in Cambridge.
The gardens and the old court are free to visit most of the time; check at the porter's lodge. Notable alumni include William Pitt the Younger (who came up at 14 and became Prime Minister at 24), Spenser, Ridley, and Ted Hughes.
