Adstock, St. Cecilia. SP 7350 3011. © David Regan (2018). Link. Grade I listed. An otherwise unidentified Methodist Chapel shows on O.S. maps on Church End at SP 7356 3013. Genuki says it is/was Wesleyan, built in 1889. Streetview saw it in 2011 - its appearance makes me wonder if it was re-built at some point.
Akeley, the site of the demolished St. James the Apostle. SP 7080 3779. © David Regan (2017). Photos of the church are available here and here (the latter slow to load, but it has a good history of the church). A former Wesleyan Methodist Chapel stands a little way east of the site of the church, on Chapel Lane at SP 7092 3780. It pre-dates a map of 1885. Streetview saw it in 2011.

Grade II* listed, wherein it's dated to 1873, by Street. A Baptist Chapel used to stand on Hog Lane, at SP 9754 0537. It's described as Baptist Chapel (General) on a map of 1887. This source says it closed in the early 1900's. Its site is shown at about the middle of a 2019 Streetview, on the left of the road.
Aston Abbotts, St. James on Cublington Road. SP 8473 2024. © Bill McKenzie. Another view, © David Regan (2019). Link. Grade II* listed. Old O.S. maps also show two chapels in the village, an Independent at SP 8467 2015, and a Primitive Methodist on The Green at SP 8480 2008. Both chapels survive, in residential use, and a little history for both is available here, where it says that the Independent was also later P.M. The Independent was seen by Streetview in 2011, and the Primitive Methodist in 2021 (its date-stone for 1832 can be seen by zooming-in). O.S. maps show The Abbey at the west end of the village. According to its Wikipedia entry it got its name from having been built on land formerly owned by St. Albans Abbey.

A Wesleyan Methodist Chapel still stands at the corner of Burcott Lane and the A418, apparently now in commercial use. It was seen by Streetview in 2008. A short distance to the west on the A418 is a former Baptist Chapel - it was also seen by Streetview in 2008. The Mission Hall stood behind roadside buildings, also on the A418, at SP 8387 1557. Aerial views suggest that it hasn't survived. It stood behind the buildings (or their predecessors) seen here in a Streetview from 2021.

Labelled on a map of 1971 as The Bourne End Methodist Church, it seems to have survived into the 1980's at least, but it has since closed  (Wikipedia says it closed in 2002) and is now a nursery school. Streetview only provides a poor view (from 2018), but the nursery website provides a better one. SU 8956 8713. Cores End U.R.C. (previously Congregational) stands on Kiln Lane at SU 9038 8729. A date-stone dates it to 1804, replacing an earlier chapel of 1768. Another refers to an enlargement in 1881. All © Chris Kippin (2021). Link, with a useful history here. Grade II listed.
Bow Brickhill, All Saints on Church Road. Two extra views - 1, 2. SP 9114 3441. All © David Regan (2019). Link. Grade II* listed. Wesleyan Methodist and Congregational Chapels are indicated on the large scale O.S. map of 1901. Both are on Station Road, the Wesleyan at SP 9060 3459, and the Congregational at SP 9044 3463. The latter has gone, its site now the parking area in front of houses (2021 Streetview). The Wesleyan site is now occupied by a school. Its grade II listing makes no mention of it having previously been a chapel, so does anything survive of it? The old school building has the same footprint as the chapel, with the exception that it extended onto what is now the adjacent parking area.

Buckland Common, the former Baptist Chapel (originally Particular Baptist), now a private residence called Chapel House. The village Wikipedia entry dates it to 1860 to the 1980's. SP 9212 0714. © Les Needham. The village also had an Anglican Chapel of Ease (wooden), mentioned in the aforementioned Wikipedia article, which dates it to soon after the Baptist Chapel, and "pulled down in about 1939". The path which probably lead to it can be seen in this Streetview from 2019. The church stood a little further back than, and left of, the building among the trees. SP 9210 0716.

Cuddington, St. Nicholas. Two views of the interior - 1, 2, the chancel and the font. SP 7374 1121. Link. Grade II* listed. The Methodist Church on Lower Church Street was built as Wesleyan (SP 7381 1129). It pre-dates an old O.S. map of 1899, and it had a predecessor on Holly Tree Lane. Holy Tree Cottage occupies the same footprint as the old chapel, though judging by appearances on a 2019 Streetview, little or nothing remains of the chapel (unless you know better!). Link. All © David Regan (2019). The village also used to have a Baptist Chapel on Dadbrook. This source dates it to 1831 (and the Wesleyan to 1894). The garages seen in this 2021 Streetview now stand on its site. An old photo of it can be found here (which dates it to 1829-1993). SP 7386 1105.

Dagnell, All Saints. SP 9917 1628. © Bill McKenzie. Link. Grade II listed. The village also used to have a Wesleyan Methodist Chapel, on Main Road South, at SP 9934 1610. Pre-dating a map of 1884, it seems to have survived into the second half of the last century, but has been demolished, as this Streetview from 2019 shows.

On a map of 1881 there's a Primitive Methodist Chapel on Aylesbury Street at SP 8815 3394. In 2021 (Streetview) there was an Indian Restaurant on the site. Another vanished chapel was the Baptist Chapel on Aylesbury Street, at SP 8818 3387. It's called Spurgeon Memorial Church here, where there is a photo, and it's dated to 1892. In this 2021 Streetview, it would have stood partly under the flats at the left, extending onto the garage forecourt. The cemetery off Aylesbury Street used to have two mortuary chapels. These were Nonconformist at SP 8796 3369, and Church of England at SP 8796 3372. Only the latter survives, and it was seen (distantly) by Streetview in 2021. The other chapel stood a short distance further left.

Another anomaly is that while I was looking on Streetview for another place of worship, shown on the same map at SP 8497 5036, on Common Street, I found Union Chapel (2009 Streetview).
