St Barnabas is a Grade I listed Norman church. Its central tower dominates the village – the roof is said to be one of the highest points in Essex. The tower walls are of re-used Roman brick quoins, iron stone, and flint. The belfry windows are surrounded with round columns with modelled faces. The body of the church have limestone dressings and Roman cement cappings on the north transept. The chancel was rebuilt in the early fourteenth century, and the nave in the nineteenth century.
Helped by a £7,000 National Churches Trust Community Grant, St Barnabas will install an accessible toilet and baby changing facilities. There are currently no toilet facilities for worshippers or visitors. This will be of particular help to parents with younger children and enable the church to welcome visitors who have travelled long distances for christenings, weddings, and funerals.
