The School of Pythagoras is the oldest building in St John's College, Cambridge, and the oldest secular building in Cambridge, England.
[4][5] The School of Pythagoras was originally built around 1200, before even the University of Cambridge existed.
In the 16th century, a small manor house was added to its west side.
[6] The School of Pythagoras is now used as the College Archive Centre.
Previously it was used as a theatre and the base for the St John's College Dramatic Society; Douglas Adams appeared there in a revue in 1972.
