A Baptist Church once stood on St. Leonard's Street, at NS 8844 4371. The earliest map I can find which labels it (though only as Ch.) is from 1940, and it's now in commercial use. Its POWiS entry dates it to 1904, and implies that it survived until at least 2003. A photo would be useful, as they describe it as a corrugated iron chapel (which would be unusual in a town centre church), but I've not been able to locate one - can you oblige? The site can be seen here in a 2008 Streetview.

The former Salvation Army Citadel on West Port. Its POWiS entry says the Army left at some point, when it was replaced by a Pentecostal Church, and later came under the S.A. again. At the time that entry was written (2003), it was in use as a museum, which a later (2008) Streetview confirms, but by 2015 the museum sign had gone, and at the time of the Streetview vans visit in 2018, it wasn't apparent to what use the building was being put. NS 8797 4375

Smyllum Park was an R.C. orphanage, with a private chapel. Its POWiS entry dates it to 1883, "probably by Peter Pugin". The chapel has been demolished, and housing built on the site, which can be seen here in a 2010 Streetview. NS 8932 4362.
