Corpus Christi University of Cambridge was founded in 1352 by two citizen guilds in Cambridge, something of an anomaly given the wealthy patrons of most other colleges. The college crest, a pelican plucking her breast and feeding the blood to her young, is a popular symbol of Jesus Christ's sacrifice. Entering New Court, the visitor will see, to the right, the Parker Library, established by Elizabeth I's Archbishop of Canterbury, Matthew Parker. His interfering disposition gave English the term nosy parker. A passageway to the left leads to Old Court, the oldest surviving college court in all of Cambridge (and Oxford). Famous alumni include Christopher Marlowe and Christopher Isherwood. Wheelchair users should note that there are some steps. The college has unpredictable opening hours.
