Columb John (today "Columbjohn") in the parish of Broadclyst in Devon, England, is a historic estate that was briefly the seat of the prominent Acland family which later moved to the adjacent estate of Killerton.
Nothing of the structure of the Acland mansion house survives except the arch to the gatehouse, dated about 1590,[1] and the private chapel, restored in 1851. The site of the former mansion house is one mile due west of Killerton House.
