Barnes
After languishing for a long time on the long-term unsolved page, Jay Priest has resolved the following mystery.

Christ Church (1874), on Christchurch Road. This old postcard, from Steve Bulman's Collection, was of long-standing in the "Unknown" section. A church with an unusual spire - and the sender has written this - "I daresay you recognize the old church, although they have omitted to print the name....". Although originally identified as St. Augustine in Dudley, it certainly wasn't that, since a photo has now been sent in, and it can be seen on the Dudley page. Thanks are due to Garry Barr for providing the final identification, and this confirmatory Link. A modern view of the church - though the trees are hiding it rather well. © Gerard Doherty (2011).

The former West Street Chapel has a long and varied history. Built in 1700 for French Huguenots. In 1743, the Wesley brothers took it over as a Methodist Chapel, the first such in London. In 1799 it became Free Episcopal (i.e. CoE), and was then successively Irish Anglican, Evangelical Anglican, a Chapel-of-Ease to St. Giles, and is now in commercial use. © Gervase N. E. Charmley.

Cranford
Google Maps says that Calvary Baptist Church stands on High Street, at number 53. The house at left in a 2022 Streetview is number 55 (57 is further to the left), so presumably the right hand part of that semi-detached is 53, but there is no visible signage, and it doesn't seem to have a web presence. Can you confirm if this church exists in this location?

It says that after the present church was built, the 1918 church was used as the parish hall and sacristy. I haven't been able to confirm it, but the pinkish building visible in this 2019 Streetview attached to the rear of the church is a plausible candidate for the 1918 church.

Howard Richter has advised that this was the Anglican St. Peter, and shows as such on the 1980-1 1:2500 O.S. map. We learn from here (scroll to about 1/3 of the way down) that it was originally a tin tabernacle chapel of ease of 1884. This stood a few yards south at about TQ 3119 8917. The present building was built 1897-1905, and damaged during WWII. The congregation merged with that of Christ Church in Tottenham in 1977, and St. John was declared redundant in the following year. The Greek Orthodox Church took over in 1983, and the church has been extensively decorated, which (in part) is the reason for it's grade II* listing.

Cornerstone Church (1998) on Canterbury Road stands on the site of St. Paul. In the 1990's, the parish had two churches, St. Catherine and St. Paul.

St. Margaret. One of London's lost churches, having been demolished in 1974. From an old postcard (franked 1907) in Steve Bulman's Collection. As advised by Mike Berrell, this website confirms the identification. A mystery photo previously in the "Unknown" section came from Mark Wilson who discovered a photo album in a skip in Dagenham of a church interior, which has a seven-light East window with rose window above. The rather awkward transition from the rose to the junction of the 2nd and 3rd, and 5th and 6th lancets are unusual.

One of Judy Flynn's postcards (previously in the Unknown section) - labelled as St. John the Evangelist and Queen's Road. From the publisher on the back (Hickox & Son, Finsbury Park (London)), Judy thinks that this is the demolished church of St. John which stood on Gloucester Drive and Queen's Drive, Stoke Newington, now replaced by a modern church, visible on Google Earth here. Certainly the boundary wall looks similar. Can you confirm Judy's suspicions? Brian Curtis suspects the identification is sound, and has supplied links to the following evidence - description (the central tower which it mentions must be hidden by the gable end), maps on http://www.old-maps.co.uk/maps.html show that the situation of the church at the junction of the two roads is identical, and the information that the Queen's Road was changed to Queen's Drive after WWII. Janet Gimber concurs, and has drawn my attention to the Google Earth aerial view, and old maps, which leaves no doubt.

Declared redundant in 2003, it was demolished the following year, and the replacement building includes a church and community space. A short history is available here (.pdf), which includes a photo of the former church. TQ 314 799. © Chris Kippin (2018).

Welling
Welling Evangelical Free Church on Upper Wickham Lane and Balliol Road. This shows on a map of 1909 as Primitive Methodist. It was relatively new at this time, as it doesn't show on the edition of the late 1890's. TQ 4670 7635. © Alan K. Taylor (1985). A more recent view is available on Google Streetview here (2018). Almost exactly opposite in a terrace, stands a Redeemed Christian Church of God (Streetview). Very close by is S and R Domestic Appliances (Streetview). This stands on the site of (and may include fabric of) Bethel Baptist Chapel, which shows on a map of 1864. This was Wesleyan Methodist by the time of the 1896 map.

West Drayton
St. Catherine of Alexandria (R.C.) on The Green was seen by Streetview in 2021. Its grade II listing dates it to 1868. TQ 0585 7947. Link.
St. Martin has fabric dating back to the 13th century. TQ 0616 7954. From an old postcard in Steve Bulman's Collection. Another view, © Christopher Skottowe (1959). Link1. Link2 has much on the monuments and brasses, and also a photo of two Burne-Jones windows. Grade II* listed.
The Chapel (Baptist) on Swan Road, as seen by Streetview in 2021. TQ 0601 7975. Link. Older maps mark a Baptist Chapel on Money Lane. It survives, and has a date-stone for 1827. It was seen by Streetview in 2018. TQ 0567 7942. This source says that it was also home to a congregation of Old Catholics, from no later than 1950 to no later than 1958.

St. Mary on Broadmead Gardens. From an old Christmas card in Christopher Skottowe's collection. A photo taken from a similar position in 1935, and two of the interior - 1, 2, all taken by Christopher's grandfather. Another old photo is also from Christopher's Collection, and can be dated to before 1908. Link. Its ancient history can be seen here; more recently, Christopher advises that a new church was built in 1958 (incorporating the old church as the Lady Chapel), and refurbished in 2009-10. The prior images in this entry pre-date these changes. The 2019 Streetview shows the present church. Note also the Seventh-day Adventist Church to its left, better seen here. A photo of the new church was an entry on the Unknown's page, and solved by Janet Gimber. West Twyford's Wikipedia entry says that the 2010 renovation saw the newer church changed into a community hall, with the old chapel re-dedicated as the church. © Christopher Skottowe.

Willesden and Willesden Green
Beulah Apostolic Church on Conley Road and Church Road. This is a recent build, as the 2012 Streetview shows a different building, though still Beulah Apostolic. TQ 2138 8454. The earliest map I have access to which shows a church on this site is of 1893-4, where it's labelled as Chapel (unreadable). It carries on being labelled just as Chapel, until a map of 1896 labels it as Chapel (Disused). A 1915 map has it as (I think) Mission Hall, 1935 as Hall, 1955 and 1972-6 as Willesden Evangelical Church, and 1988-96 as Ch. © Derek West.

Elim Church on Willesden High Road. Commonly known as Church on the High Road, this was originally a Congregational Chapel, the second in the area, and it pre-dates an O.S. map of 1893. TQ 2210 8475. © Judy Flynn (2014). Link. The predecessor Congregational Chapel seems to have been built some time before 1850. It appears on a map of that year, but is un-named; however, a building with the same footprint is identified on a map of 1865. Demolished at some unidentified date, the site can be seen here on a Streetview, and it would have stood between the trees and the tall green lamp-post. In the same 2015 Streetview can be seen Bethlehem Ministry, of the Assemblies of God, in a former cinema. It can also be seen here in 2014. A 2018 Streetview shows the building boarded up, though whether this was because of closure or refurbishment work is unknown at present. The grid reference for this is TQ 2217 8480. Howard Richter advises that there was also a Salvation Army Citadel on the same road, about opposite to the Ministry, and now replaced by a block of flats (which can be seen by rotating the 2018 Streetview)

St. Philip. From an old postcard in Reg Dosell's Collection. This link says that the congregation now shares use of the local Methodist church for its services, so St. Philip may no longer exist - can you confirm? Janet Gimber has advised that the church was partially demolished in 1978, with the remainder following in 1984. Further details here.
