This church has an elegant belltower porch (1706) which has a dome with a lantern, and a spire rests on an octagonal belfry. Modified in the late 18C, the cradled nave is supported by thin ionic columns alternated with splayed high windows. A statue and a stained glass window (on the right) depict Magnus, master of the Orcade Islands in the 12C and martyred by decapitation.
