Bonhill, the Parish Church (CoS) on Main Street. Another view. POWIS dates it to a re-build in 1834-6, recycling stone from its predecessor. NS 3948 7963. Both © Jim Parker (2014). Facebook. Category B listed. There used to be a Free Church on Main Street, at NS 3953 7942. Pre-dating a map of 1864 (though with a different footprint to the later church), it still seems to have been in active use in the middle of the last century, but has since been closed and demolished. POWIS has dates of 1846-1974. The housing on its site was seen by Streetview in 2011. Also gone is a U.P. Church on Main Street. The house on its site was seen by Streetview (from Third Avenue, Main Street beyond the trees) in 2023. POWIS dates its closure to sometime after 1975. NS 3969 8005. Also included on POWIS is St. Ronan (R.C.) on Ladyton. Built in 1977 it was destroyed in a fire in 2011 and never re-built. The map included in the entry implies a grid ref. of circa NS 4012 7931. I haven't been able to find a photo. BBC news report on the fire.
Bowling, the former Parish Church on Dumbarton Road. Another view. Both © Jim Parker (2014). Link.

Dumbarton.

Gartocharn, Kilmaronock Church (CoS). An 1813 re-build on an ancient site, this church is also known as the "Summer Church", as it is only used in the warmer months. Another view. NS 452 875. Link. Grade B listed. It should be no surprise that there is also a "Winter Church", which is in the village of Gartocharn, at NS 428 863. Built as a Relief Church in 1772, re-built 1911, it shows on the 1862 OS map as United Presbyterian. Another view. Grade B listed - beware the reference therein to this being the Summer Church, an error, which the history confirms. There is mention here (2010) of the proposed disposal of this church, but this news item (scroll to the end) implies the Summer/Winter alternation was still happening in 2013.
