Trinity College is one of the largest, wealthiest and most attractive colleges. It was established in 1546 by Henry VIII, whose statue peers out from the top niche of the great gateway (he’s holding a chair leg instead of the royal sceptre, the result of a student prank).

Beyond the Great Court are the cloisters of Nevile’s Court and the dignified Wren Library, built by Sir Christopher in the 1680s.
