The oldest (and also one of the smallest) of Cambridge's colleges, Peterhouse was founded in 1284.

 Its historic hall and storeroom on the south side of Old Court are the earliest of the original 13th-century buildings. Among those who studied here were Cardinal Beaufort, chemist Henry Cavendish, and poet Thomas Gray. 

Worth seeing are the stained glass windows in the chapel (imported from Munich in the 1850s) and the 17th-century altar window.
