Michaelhouse is a former college of the University of Cambridge, that existed between 1323 and 1546, when it was merged with King's Hall to form Trinity College. Michaelhouse was the second residential college to be founded, after Peterhouse (1284). Though King's Hall was established earlier in 1317, it did not acquire actual premises until its re-foundation by Edward III in 1336. The name Michaelhouse is now used for St Michael's Church.
