The porch doorway, two interior views - 1, 2, the altar, and the font, all © Chris Stafford (2013). Link. Grade I listed. An Independent Chapel (later Congregational) is labelled on old O.S. maps at TL 8009 4168. It pre-dates the earliest map available to me (1876), and seems to have been closed before 1957. The site of the chapel and adjoining burial ground, which has been redeveloped for housing, can be seen in this 2009 Streetview. I've been unable to find a photo, or any substantial information, about this chapel.
Belchamp St. Paul, St. Andrew, which stands about a mile N.N.E. of the village, at TL 7983 4346. Three interior views - 1, 2, 3, the altar, one of the many fine bench-ends, and the font. All © Chris Stafford (2013). Link. Grade I listed.

Berden, St. Nicholas. Another view, a fine window, two interior views - 1, 2, and the font. TL 4677 2963. All © Chris Stafford (2013). Link. Grade I listed. The 25" O.S. map of 1897 marks a Wesleyan Methodist Chapel at TL 4694 2985. The chapel pre-dates a map of 1876-7, and the latest map to show it which I can find is dated 1960. A map of 1978 shows a Hall on the same site, and it can be seen here on a Streetview of 2009. It seems to have roughly the same footprint, so perhaps all or part of the chapel survives, in what is now the village hall.

Castle Hedingham, St. Nicholas. The 6" O.S. map of 1897 says St. Nicholas's Church (Vicarage) on Site of St. James's Church. A Norman door, two interior views - 1, 2, the hammer-beam roof, the very fine piscina and sedilia (with much C19/20 restoration, says the grade I listing), stoup, pulpit and the font. TL 7846 3560. All © Chris Stafford (2013). Link. The War Memorial in the churchyard is separately listed as grade II. Old maps show a Congregational Chapel on Queen Street, at TL 7840 3539. It was seen by Streetview in 2009. The sign had gone by 2016, so had presumably closed by then. Grade II* listed. There was at one time a Priory (Benedictine Nunnery) to the west of the village at TL 77790 35560 - grid ref. from this source, which says that only a small fragment of masonry survives. If the grid ref. is accurate, the fragment should be somewhere along the left-most hedge-line - seen in Streetview from 2021.

It's dated here to 1877-8, where it also says that there was a preceding chapel of 1844 - though whether it was on the same site isn't clear. It was seen (distantly) by Streetview in 2021. TL 4815 3234.

Christ Church on Stoneham Street. TL 8499 2274. Link. Wesley Hall, also on Stoneham Street, appears to be the hall for Christ Church, but was presumably a Wesleyan Methodist Church at some point. Circa TL 84965 22670. Old Chapel on Church Street was Baptist (as shown on map of 1875), and had been opened in 1855. It was preceded by an earlier chapel of 1829, also on Church Street, so perhaps on the same site. Prior to this, the congregation, formed at least as early as 1745, met in private houses. TL 8514 2271. The Catholic Church of St. Bernard of Clairvaux on Stoneham Street. TL 84965 22768. Link. The former Friends' Meeting House (1878) on Stoneham Street is now the library. It stands on the site of an earlier Friends' Meeting House, which, according to the plaque, was purchased in 1673, and so presumably a pre-existing building. TL 84946 22729. An unusual entry for this website is the Woolpack Inn on Church Street. The plaque provides the explanation. TL 85312 22944. All © Steve Bulman (2016).

The 1" O.S. map of 1956 shows a place of worship south of the village on Mill Road at TL 5438 2800. It didn't exist in 1920, and I haven't been able to discover anything about it.

Middleton, All Saints. Previously in the "Unknown" section, this postcard (franked 1905), is from Judy Flynn's Collection. Brian Curtis, Simon Davies, Janet Gimber and Greg Mishevski all rapidly identified it, providing the following information and links. A photo of the church in 1895 (with less greenery), a drawing from the 1940's. The spire was subsequently removed in the 1950's, when other restoration work was carried out (link, see page 5, para 4). Church Plans On-line says that an application for a grant was made in 1951, so the spire was perhaps removed in the early 1950's. A modern photo. Link. Grade I listed - link.
Mistley, Mistley towers, the remains of Mistley Thorn Church, originally of 1735, later embellished by the towers added by Robert Adam in the late 1770's, and which remain today.

Waltham Abbey, the Parish Church of Waltham Holy Cross. Not the Abbey, as this has always been the parish church. The adjacent abbey was a victim of Henry VIII, but the parish church was unmolested. Originally a church was dedicated here in 1060 by the later King Harold. The core of present church has more or less the same footprint. Two further views - 1, 2, and an interior view, all © Christopher Skottowe (1964). Christopher Skottowe has an old album containing (among other things) a sketch of a church, which has previously been in the Unknown section. Though there's no indication of the date of the sketch, it is probably from late Victorian times. Simon Davies has identified it as Waltham Abbey in Essex, before Victorian alterations increased the height of the tower. Two additional views - 1, 2, interior view, the altar, and a fine monument. King Harold is allegedly buried here - a stone marks the site. All © Peter Morgan (2015). Link1. Link2. An old engraving of the church can be seen here and (coloured) here.
