Banff on Wikipedia.

There are a few scant historical references to a Carmelite Friary in Banff, but no traces remain, and its location is uncertain.

Harvest Centre (Riverside Church) on Castle Street was originally a Free Church. It was seen by Streetview in 2021, and this source dates it to 1844. NJ 6884 6411. Link. Category B listed.

The former Methodist Church is on Seafield Street and Reidhaven Street, and was seen by Streetview in 2021. A stone over the doorway declares the church to have originally been Wesleyan, dated here to 1878. It seems to have still been active at the time of the previous Streetview visit in 2016. NJ 6875 6424. Category C listed, which says it had two predecessors. One of these is stated to have been what is now 27 Castle Street, seen by Streetview in 2021. It's dated 1820-30 (though the Wesleyans came later) in its Category C listing.

Our Lady of Mount Carmel (R.C.) on Sandyhill Road as seen by Streetview in 2022. It's dated here to 1870. NJ 6871 6356. Link.

St. Andrew (Episcopal) stands on High Street, and was seen by Streetview in 2015. It's dated here to 1833. NJ 6890 6391. Link.

St. Mary (CoS). NJ 6889 6380. © Alex Parker. Link. Category B listed, wherein it's dated to 1790, with later additions, and it says that it was a replacement for an earlier St. Mary, the remains of which stand in a graveyard bounded by Carmelite Street, Church Street, and High Shore. Seen in a Streetview from 2010, more information can be found here, where it's dated to 1471 (there was a yet earlier church on the site) to 1797, when most of it was demolished. NJ 6905 6405.

Just a few yards east of the Methodist Church, on Seafield Street, formerly stood a United Free Church, shown on a map from 1904. I haven't been able to find any further details, or a photo. There's a house on the site today, seen by Streetview in 2021.
