One citizen of Sudbury, Archbishop Simon Sudbury showed that not even the Tower of London guarantees safety. On 14 June 1381 guards opened the Tower's doors and allowed a party of rebellious peasants to enter. Sudbury, inventor of the poll tax, was dragged to Tower Hill and beheaded. His body was afterwards buried in Canterbury Cathedral, but his skull is kept in St. Gregory's with St. Peter's Church, one of the three medieval churches in Sudbury. Simon's concerns for his native town are reflected in the founding of St Leonard's Hospital in 1372, a place of respite, towards Long Melford, for lepers. For the College of St Gregory, which he founded in 1375 to support eight priests, he used his father's former house and an adjoining plot.
