Cruggleton Castle is reached by taking the path from Galloway House Gardens. The church is on the B7063.
Occupation of the site at Cruggleton Castle probably goes back to the late Iron Age, although the stone built phase of the castle probably dates to the 13th century and was probably built by John Comyn.
According to an unbroken tradition dating from the earliest times and confirmed in the writings of the Venerable Bede in the 8th century, a holy man named Nynia, born among the British people, introduced the Christian faith into a significant part of the land now known as Scotland long before the coming of Saint Columba.
