Lying a quarter-mile (0.5 km) southwest of the Midlothian village of Crichton, and just to the north of Crichton Castle, the Crichton Parish Church was established as a Collegiate Church in 1449 by Sir William Crichton, laird of the nearby Crichton Castle and Chancellor of Scotland. One of few remaining pre-Reformation collegiate churches which are still in use in Scotland, the Parish Church of St. Mary and St. Kentigern comprises a chancel and two transepts built in red sandstone; there may once have been a nave, but the only traces now are ragged stone work on either side of the entrance and traces of the roofline on the tower.
The vaulted interior was furnished during a major restoration completed in 1899, and it was then that the stained glass was installed.
No longer in regular use for worship, the church is open to visitors in the summer months.
The kirkyard include some interesting old grave stones and three well-maintained cast-iron memorials for George Douglas (d.1841), of the Broughton Foundry in Edinburgh, and his family.
