Glen Thorn lies about 26 kilometres north of Adelaide, on the left side of the road to Tarkastad. On this farm, in the Macazana Valley, there is a small church of great historical importance.

The farm Glen Thorn, in the Mancazana Valley, was granted to John Pringle (brother of Thomas Pringle, an author and the leader of the Scottish Party) in 1824, and it was he who commissioned the building of this church. The church was built of plastered sandstone in 1843 with the assistance of the British troops (93rd Regiment of Foot – Argyle & Sutherland Highlanders) stationed at the Old Post fort. The first minister was the Rev. John Forbes Cumming. It is the second oldest Presbyterian Church in South Africa and had a resident Minister until 1953 – the Rev. Sam Workman. The congregation was drawn from the Mancazana Valley and, from 1956, fell under the Adelaide Presbyterian Church. Monthly services were held until Covid and it has since sadly never reopened. The congregation has been decimated over the years, but old families are still about, and an annual carol service is held when family and now far-flung members gather to celebrate Christmas.

Direction: Take the R344 north from Bedford towards Tarkastad. Travel for 26,5km. Take the turn-off to the left (Glen Thorn). The church is 5,5km from turn-off.
