Kilmaluag, the former Kilmaluag Church of Scotland Mission at NG 431 743. It can be seen on Streetview here, and is described here as "a self-catering retreat house for ministers and church staff". Map evidence suggests that it was built between 1955 and 1966, © Martin Richter (2013). Howard Richter advises of an additional church, Kilmaluag Free Church Mission, which is shown on old maps at NG 4385 7400. It can be seen on Streetview here. Its present status is not apparent.

Sconser, Kingdom Hall of Jehovah's Witnesses. NG 5215 3217. © Tim Flitcroft (2012). Howard Richter has advised of a former Church of Scotland building nearby, at NG 5167 3193. The oldest available map shows it as a "School (Boys and Girls)" in 1877, but by 1903 it was a Mission Room. Enough can be seen on a Streetview of 2011 to show that it is still extant, and an internet search shows that it is now in use as holiday accommodation. Link.
Skeabost Bridge, Snizort Free Church of Scotland (1847). NG 407 490. © Dennis Harper (2013). Link. A 2011 Streetview provides a useful alternative view. Grade C (S) listed. Howard Richter advises of a nearby demolished church, South Snizort Church of Scotland. It was still standing, and presumably active, when a map of 1964 was published. The site, visible in a 2011 Streetview, shows a modern house, though Howard suspects it stands rather further back from the road than the church. NG 4058 4908.

The site is seen here on Streetview. © Martin Richter (2013). Link.
