Augustine United Church on George IV Bridge. NT 2571 7338. © Bill Henderson. This must surely be the same church as that listed in Pevsner as Augustine Bristo Congregational Church - it's certainly labelled as Congregational on older maps. Another view, © Steve Bulman (2022). Link.

The former Lady Yester's Church (1805) on Infirmary Street, now used by the university as its carpentry division. It stands near to the site of the original church (1647) which was built on the site of the Blackfriar's Monastery. The 1647 building was damaged by Cromwell's army in 1650. Janet suspects that the building at the left of the photo was a New Jerusalem Church - can you confirm? © Janet Gimber (2012). Link.

The former Tolbooth Church (1842-5) on Castlehill. Designed by J. G. Graham, and A. W. N. Pugin, it was built as Victoria Hall to house the General Assembly of the Church of Scotland meetings, and as a church for the Tolbooth congregation. It ceased to be used by the General Assembly in 1929 but continued in use as a church. From 1956 until the 1980's it was known as the Highland Tolbooth St. John's Church. Now used as offices and a cafe, and for performances during the Edinburgh Festival, it was re-named "The Hub" in 1999. © Bill Henderson. Another view, © Janet Gimber (2012). Link.

This former church building is on Holyrood Road. Jean Walker advised that it has a plaque on it identifying it as the "Old Kirk". Glen Jones has further added that it is also known as the Great Kirk, and was built in 1881 for a congregation which had previously used St. Giles. It ceased use as a church in 1944, when the church and its adjacent hall were purchased by Moray House (part of Edinburgh University) who converted it to use as the Music and Educational Handwork departments in 1949. It has also served to house Moray House's Building Services, but has stood empty for some years.
