Glenorchy Parish Church stands on an island site between the rivers Orchy and Orchy Bheag near the village. The category A listed building, constructed 1810–11 on the site of at least two earlier churches, is a rare example of an octagonal plan with adjoining tower. The little-altered, white-harled (roughcast) church has been restored to its original appearance in recent years. The site is probably early Christian in origin, and is associated with Saint Conan. The large churchyard contains examples of medieval grave-slabs in the 'West Highland' style, which may have originally covered the graves of early chiefs of the Clan MacGregor and their relatives. They show warriors in contemporary armour, interlace and other motifs.
