King's College Chapel is a splendid example of late Gothic (Perpendicular) architecture.
It was started in 1446 by Henry VI (1421-71) and took over a century to build.
It has the largest fan vault in the world and some of the finest medieval stained glass.
It is also the venue for the Christmas Eve service, A Festival of Nine Lessons and Carols, which is broadcast to millions around the world.
