St Machan's (originally St Paul's) was built in 1846 as a permanent place of worship for the Catholic Mission in Campsie, established in 1831. It was the first post-Reformation Catholic church in the central belt of Scotland outside the main cities and towns of Glasgow, Edinburgh, Paisley, Falkirk and Stirling. It was renamed St Machan's in 1881 by Father John Honorius Magini, in honour of the Saint associated with nearby Campsie Glen. The church contains a number of interesting historical objects, especially relating to its 19C history.
