The Church of St Mary is a Church of England parish church in Chadwell St Mary, Thurrock, Essex. The church is a Grade I listed building.[1] Together with Emmanuel Church, it forms the Parish of Chadwell St Mary in the Diocese of Chelmsford.[2]
The original Chadwell parish church was dedicated to the Virgin Mary and this is the source of the suffix "St Mary" in the modern name. It is a grade I listed building located at the crossroads overlooking the marshes. There was a church in Chadwell before the Norman conquest. The present church has a number of Norman features and probably dates to the 12th century. The tower was built in the early 16th century.[3] The church contains an early memorial brass to Cicilye Owen (died 1603), the wife of Thomas Owen of London, who was a merchant tailor. The church has an extension on the south that was built at the beginning of the 20th century.
On 8 February 1960, St Mary's Church was designated a Grade I listed building.
The parish is within the Evangelical tradition of the Church of England. It no longer rejects the ordination of women.
On the north side of the church is a war memorial to eight of Chadwell's dead from the World War I. In 2006, five names of World War II dead were added to this memorial.[4]
Close to the church is the gravestone of Elizabeth Manning. When she died in 1805, her will was contested and this led to a landmark ruling that has been quoted frequently over the years.
Among the other stones in Chadwell churchyard there is a memorial to Kadzuo Yamazaki (or Kazuo Yamazaki), a 22-year-old Japanese naval officer. He died on 13 July 1899 in a fire on board the SS Kawachi Maru, while she was in Tilbury docks.[5] The stone has an inscription in both English and Japanese.
