King's College, founded by Henry VI in 1441, is the most famous of the Cambridge colleges and the one most visitors spend their money to enter. The college's front court, facing King's Parade, is a composition of the Gothic chapel (1446–1515), the Gibbs Building (1724), and later structures that together make one of the grandest enclosed spaces in English architecture.
The Backs at King's are particularly impressive — the college lawns run down to a broad sweep of the Cam backed by Clare's gardens. Entry is charged except during services. The chapel is worth every penny of the admission; the lawns and gardens are worth seeing from the river on a punt.
