One of Edinburgh's most famous churches, Greyfriars Kirk was built on the site of a Franciscan friary and opened for worship on Christmas Day 1620. Surrounding the church, Greyfriars Kirkyard is one of Edinburgh's most evocative cemeteries.
In 1638 the National Covenant was signed in the kirk, rejecting Charles I's attempts to impose episcopacy and a new English prayer book on the Scots, and affirming the independence of the Church of Scotland. Many who signed were later executed at the Grassmarket and, in 1679, 1200 Covenanters were held prisoner in terrible conditions in the southwestern corner of the kirkyard. There's a small museum inside the church.
