Aberlady, the Parish Church. NT 4619 7985. © Bill Henderson. A winter view, and the East Window, both © Revd. Norman Faulds. Norman advises that the central panel of the window is based on Botticelli's "Madonna and Child" which is now in the National Gallery of Scotland. The fabric of the church is late C15 (tower), C16 and C17 (aisles), with a Victorian renovation (1887). Link. Category A listed. PoWiS. Older maps show a United Presbyterian Church, pre-dating one of 1854, and it had gone out of use in the first half of the lasy century. Unfortunately none of the available maps are entirely clear which building the label is meant to apply to, but I think it probably stood on the west side of The Wynd, at NT 4651 8000. If this is correct, it has been demolished, and the site is now a parking area (2024 Streetview). A little way east of the village O.S. maps mark Convent (Remains of) at NT 4711 8015. Its PoWiS entry calls it Luffness Carmelite Monastery. Some photos can be seen here, where it's called Luffness Friary. Canmore.

Bolton, the Parish Kirk. NT 5073 7006. © James Denham. Link. Category B listed - dates it to 1809. A churchyard mausoleum is also listed as category B. It has evidently been closed as this webpage shows it as "under offer" in 2025.

Cockenzie and Port Seton, Viewforth Port Seton Gospel Hall, on Viewforth and Cope Lane. NT 4050 7585. © Bill Henderson. Link dates it to 1922. Cockenzie Old Parish Church (1838) on High Street. NT 4007 7576. © James Denham. As of 2025 Google Streetview is labelling this church as permanently closed. PoWiS. Chalmers Memorial Parish Church on Gosford Road, as seen by Streetview in 2023. As of 2025, Google is also labelling this church as permanently closed, although its website is still active. Its history page dates it to 1904, as a Free Church. NT 4031 7567. PoWiS. Tranent with Cockenzie Methodist Church (2023 Streetview) is on Edinburgh Road and West Lorimer Place. Its date-stone is for 1878, as Primitive Methodist. NT 3990 7553. Link1. Link2. Elcho Place Hall (2023 Streetview) on High Street is also used for worship - their website is here. PoWiS lists a Fishermen's Bethel on New Street, but gives no further details. It pre-dates a map of 1894, and was seen by Streetview in 2022 - unfortunately the date-stone is weathered to un-readability, and the building is evidently now in domestic use. NT 4016 7570. The same map also shows a F. Church (presumably Free Church) nearby at NT 4011 7571, on School Lane. It was no loner marked as a place of worship by the time of a map of 1955. The housing on its site was seen by Streetview in 2022. There was also a Baptist Chapel, shown on a map of 1894 as Bapt. Chapel (General), on Main Street. The map seems to be indicating a building in the middle of a terrace on the south side of the road. If this correct it will have been at circa NT 4016 7577, and Streetview saw the buildings on its site (at the left) in 2023.

Dirleton, the Parish Church. Two more views - 1, 2. NT 5127 8422. All © Steve Bulman (2021). Link, which dates it to 1612, on the site of a medieval predecessor. PoWiS. The village also had a Free Church, now demolished. It stood off Manse Road, south of the western corner of the village green, at NT 5146 8381. It's dated here to post-1843 to 1936. Its site isn't viewable on Streetview, but the access road to where the site was is seen here in a Streetview from 2020.
Dunbar, the Parish Church on Queen's Road. Large scale O.S. maps say about this church as (e.g.) Church on Site of Collegiate Church (A.D. 1342). NT 6817 7858. © Bill Henderson. Link. Category A listed, wherein it's dated to 1818-21. PoWiS. This postcard view of an interior (from John Bowdler's Collection) was in the Unknown section for many years, before finally being identified by Janet Gimber as the interior of St Anne's Episcopal Church, on Westgate. Its exterior can be seen in a 2022 Streetview. NT 6781 7905. Link. PoWiS. Older O.S. maps also show R.C. Chap. on Bayswell Road at NT 6778 7908. PoWiS calls it Our Lady of the Waves, and is dated here to 1877. It was seen by Streetview in 2018. A map of 1854 shows a United Presbyterian Church at NT 6822 7875. It had been demolished no later than 1893. Its site was seen by Streetview in 2022 - effectively the gap between the two blocks of housing. Curiously, another United Presbyterian Church shows on the same 1854 map nearby, at NT 6805 7882, on Church Street. It had also gone by 1893, and its site was also seen by Streetview in 2022. The towns former Free Church (2022 Streetview) stands at the end of High Street, at NT 6801 7872. It's now in commercial use. Category B listed - dates it to 1850. PoWiS.

Discovery Church is based in a house on Grahame Place, but meets in a number of locations. I think it's one of the houses on the street seen in a Streetview from 2022. Link.

Three views of the former United Presbyterian Church on The Square - 1, 2, 3. What may be this building shows on the OS map of 1854-5; it is certainly shown on the 1894 map, and on the next map (1907, which is after the union) it shows as "U. F. Church". It continues as such on the 1938 map, but by the 1957 edition it shows as "U. F. Church (Dis.)". There is some indication that it was subsequently in use as a Masonic Hall. NT 5919 7731. All © Howard Richter (2013). PoWiS dates it to 1770, closing in 1910, and confirming its later use as a Masonic Hall.

Gifford, the Yester Parish Church. Jim Napier and James Denham advise that the Rev. John Witherspoon, son of the one-time vicar here (also John Witherspoon), was the only cleric to sign the American Declaration of Independence (though he signed as Governor of Princeton and Principal of Princeton College), and that the American system of government owes much to this Presbyterian influence. Another view. NT 5348 6810. Both © Steve Bulman (2021). Link. Grade A listed, wherein it's dated to 1708-10. The village also had a Free Church.

A map of 1855 shows West United Presbyterian Church off Court Street, at NT 5124 7393. Only a small tower survives, seen by Streetview in 2020.

On the 1855 map, immediately south-east of St. John, was St. John's Free Church, at NT 5149 7408. By the time of a map of 1895 it was disused. Whether the building on its site (2022 Streetview) is a conversion or a later building is unclear.
