The Barn dates from 1450 and was part of an estate that supported the Abbey of Waltham. The Abbott’s hunting lodge next door was later converted into a private house and is now home to Upminster Golf Club.
Despite being known as the ‘Tithe Barn’, there is no evidence to suggest it was ever used for the collection of tithes.
The Tithe Barn stands 18 metres wide by 12 metres high and 45 metres long.
It wasn’t until 1976 that the Barn was refurbished and then opened as an agricultural museum.
