Broughtown, the Cross and Burness Parish Church. HY 6592 4080. © Martin Briscoe. In this more recent view it has a sign saying that it is the Parish Church (CoS) for the island. © Peter Amsden (2010). Older O.S. maps also show two Free Church's nearby, at HY 6625 4131 and HY 6652 4068. The first survives (I think), perhaps in agricultural use, and was seen by Streetview in 2010. The second survived until relatively recently, but appears to have been demolished or was undergoing serious redevelopment before the first (and so far, only) Streetview visit in 2010, when it was a building site.

How, the remains of the former Cross Parish Church. HY 654 392. © Martin Briscoe.

Laminess, Old Church. There is a date above the door, 1909. HY 620 373. © Martin Briscoe. Kevin Price advises that this is the former Baptist Church, and is currently (2011) up for sale.

Northwall, the disused church at HY 739 440. © Martin Briscoe. In this more recent view the building has obviously undergone some repairs. Can you advise its current usage? © Peter Amsden (2010).
