On the first floor, known since Victorian times as "Big School", is the room in which William Shakespeare is believed to have been taught. The building known as Pedagogue's House across the courtyard currently houses the school office, the offices of the Headmaster and the two deputy headmasters. Pedagogue's House, first built in 1427 and believed to be the oldest half-timbered schoolroom in England, is attached to the Old Vicarage where the Headmaster lives. Adjacent to the school site is the Guild Chapel, founded by the medieval Guild of the Holy Cross and now owned by the Stratford-upon-Avon Town Trust. Today it is used by the school for morning service and various other school events, such as the annual carol service.
