Statement of Special Interest
An outstanding post-Reformation church, with distinctive channelled broached spire, set in historic kirkyard. Sited on an ancient place of worship called Erncraig, the rectangular church was rebuilt in 1699 following a fire, then gradually extended to include the Glencorse and Woodhouselee Aisles. The Lairds and their families used the upper floors, and the Glencorse aisle has a vaulted undercroft (previously the Lairds had used lofts within the main body of the church). Robert Louis Stevenson attended the church in his youth, travelling over the Pentland Hills from Swanston. He later described it as the "most delightful place on earth." The church was used until 1885, when the present kirk was built to accommodate larger congregations due to more troops at the barracks. Robert Trotter (resident of Bush House) either repaired or added the timber spire to the old kirk, and a later descendant of the same name contributed £400 towards a new church. He also donated a field at New Milton Farm as a parish cemetery, which is still in use today. Old burial ground has interesting 'trade' gravestones (see separate listing).
The kirk fell into a state of disrepair and remained ruinous until it was re-roofed circa 2004 bringing it back into use for religious services. The interior has been consolidated but is in an "unfinished" state with exposed stonework and freestanding pews creating a picturesque atmosphere.
