Teampull Bheanáin, Medieval church on Inishmore, Ireland

Teampull Bheanáin is a stone medieval church on Inishmore with interior dimensions of roughly 3 by 2 meters, featuring high squared gables and massive stone walls. The small structure sits on a ridge and displays typical features of early Irish church architecture.

The church was built in the 11th century and served as a shrine tomb for Saint Benan, a follower of Saint Patrick. The structure is thus connected to the early phases of Christianity spreading across Ireland.

The church displays early Irish religious design with its keyhole-shaped doorway and single window oriented toward the Irish mainland. These features reflect the building traditions of the early Christian period.

Teampall Bheanáin stands on a high ridge above the southeast sea approach to Kilronan harbour, in the townland of Killeany at the eastern end of Inishmore. The narrow doorway is now secured by a stile, and the roofless interior is exposed to the prevailing wind. Below the hill lie the remains of a monastery, a round tower stump and a Celtic cross.

Unusually, the church is oriented north to south rather than the standard east to west direction, with its altar facing southward. The reason for this unconventional alignment remains unclear even today.
