King's College Chapel, Cambridge is one of the finest examples of the late Gothic style. It was built by King Henry VI, who was displeased by the excessive decoration of earlier styles. He wrote in 1447 that he wanted his chapel "to proceed in large form, clean and substantial, setting apart superfluity of too great curious works of entail and busy moulding." The chapel, built between 1508 and 1515, has glass walls from floor to ceiling, rising to spreading fan vaults designed by John Wastell. The glass walls are supported by large external buttresses concealed at the base by side chapels.
