The oldest and smallest college, charming Peterhouse was founded in 1284. Much of the college was rebuilt or added to over the years, including the exceptional little chapel built in 1632, but the beautifully restored main hall is bona-fide 13th century.
Rumours abound among students – vigorously denied by college authorities – of hauntings and spectral happenings on the site. Three Nobel Prize winners count themselves among Peterhouse's alumni.
