Biggar, Biggar Kirk (CoS). A difficult church to photograph well. Two additional views - 1, 2. Closed when I visited, this link has interior views. NT 0404 3790. Link1. Link2. Category A listed, wherein it's dated to 1545. The graveyard as a whole is Category B listed. The nearby Moat Park Heritage Centre is the former Moat Park Church (1865). Its various denominations can be followed on old maps, and Janet Gimber advises that these include United Presbyterian in 1897, United Free in 1910, the unhelpful "Church" (1940), and Gillespie Moat Park Church (CoS) in 1975. NT 0398 3785. Link. Category B listed. The former Gillespie Church, now the Gillespie Centre. It closed before 1977 (see link). Old maps show the following - South UP Church (1858), Ch. (1897), UF Ch. (1910), Ch. (1940), and in 1975 as Ch. Hall. This is presumably the Church Hall for Moat Park Church. NT 0411 3776. All © Steve Bulman (2013). St. Isidore (R.C.) on Coulter Road, as seen by Streetview in 2009. NT 0375 3748. Link.

Leadhills, Lowther Parish Church (CoS). Howard Richter advises that this is labelled as a Free Church on old maps. NS 8853 1476. The former Plymouth Brethren Meeting Hall (so identified here). The sign says "Ebenezer Hall". NS 8854 1485. Both © Steve Bulman (2019). Howard Richter has pointed out that old maps also show another church at NS 8859 1514, on Ramsay Road. It was labelled as Chapel in 1894, and Church in 1910. Since demolished, its site can be seen on a 2009 Streetview. Can you advise its denomination?
