Cromarty East Church on Church Street is in the care of the The Scottish Redundant Churches Trust. NH 7909 6727. © Martin Briscoe. Since Martin took his photo, the Trust has restored the church - two photos follow, both © John Mackie (2011) - 1, 2. Two views of the interior - 1, 2, both © Peter Morgan (2021). Link. Nearby stands this building, which looks very church-like. All of the maps I can access show it simply as Hall, but was it ever used as a church? NH 7914 6726. © Peter Morgan (2021).

O.S. maps mark St. Regulus's Chapel (Ruin) at NH 7943 6708, in an old graveyard to the south-east of the town. According to this source (which has a photo of the graveyard), nothing remains to be seen above ground, though some were visible in the 19th century.

Originally listed as a possible former church, Howard Richter has advised that it is in fact Victoria Hall, on High Street (at NH 7871 6745). Dating to between 1879 and 1906 (from map evidence), this website says it was originally a Drill Hall. As its own website says, it's now used as a performance venue. © Rob Kinnon-Brettle (2016). Added in 2021 - this source says that Free Church services are held here monthly, as an outreach from Resolis Free Church of Scotland.
