There are a number of ruined duns on Craignish, as well as cup and ring marked rocks. One such site is Dunan Aula, a cist said to commemorate a Viking prince so-named, who fell in battle against the native Scots. At Kirkton, the remains of the early 13th-century chapel of Kilmarie still stand. A chapel on this site is said to have been founded by St Máel Ruba, from whom the modern name is derived. The chapel was repaired in the 19th century, and again in 1926, and now houses a collection of 14th- and 15th-century sculptured grave slabs.
