English: Ruins of St. Thomas a Becket chapel These ruins stand along Brentwood's High Street, close to The Baytree Centre. The chapel dates back to the 13th century and all the remains now is part of the west and north wall of the nave and the lower half of the 14th century tower. The fabric of the tower shows some re-used Roman brick. The building remained in use as a chapel until 1835 and it was then used as a boys school until 1869 when it was mostly demolished.
