On the Island of Iona, close to the Abbey, stands the Parish Church of Iona. This was built in 1828 to the design of Thomas Telford, the church interior was redesigned in 1939 to make it what it is today. This was one of 32 "Parliamentary Churches" (so named because they were paid for with funds voted by Parliament) built across the Highlands and Islands to a standard design produced by the engineer Thomas Telford for a T-shaped church and an accompanying manse.

Services are held in the church every Sunday at 12 noon (11am from 19th November).

Short services are held on Tuesdays at 1pm and each weekday during high summer.
