The ruins of the old Church of Ireland in Kilmacrennan can still be seen although there is not a lot of the original building left. The most intact of what is left is the battlement tower which was added sometime in the 17th century. There are however quite a number of old graves in the grounds of the church ruins.
The ruins and graveyard are just a few moments drive outside the village. To the left of the old church ruins is the grounds and ruins of Kilmacrennan Abbey.
