Bonkyl Church (also spelled Buncle or Bunkle) (Scottish Gaelic: Bun na Cille = 'the hill foot of the church'[1]) is a Church of Scotland kirk situated at grid reference NT808595 5 miles (8 kilometres) northeast of Duns in the old county of Berwickshire.
The nearest hamlet is Preston just over 2 miles (3 kilometres) to the south-west.
There has been a religious establishment at Bonkyl since the early 12th century, and it was part of the vicarage of Dunkeld before 1275.
During the Second War of Scottish Independence the location was contested by Thomas Ughtred, a future Knight of the Garter.
It is thought to be the oldest of its kind in Scotland, having been built in the early 12th century and is a designated scheduled monument.
