Dun nan Gall is notable among the brochs on Mull because of its state of preservation and its well defined and complex internal features. It lies just a short walk south of Croig Farmhouse on the shore of Ballygown Bay and occupies the summit of a rocky knoll.  It is protected to the north east by a high, sheer rock face, but is accessible from the southwest where the cliffs diminish in height and grassy slopes offer a comparatively easy approach.  The internal enclosure 35 feet in diameter was defended on all but the north-east side by a dry-stone walls. No artificial defence was necessary to the northeast where the shear cliff offered natural protection.  The dry-stone wall remains as a low, grass-covered band of core material about 13 feet in width. Its dimensions suggest the walls could have once stood up to 30 feet high. Very impressive some 2,000 years ago.

The entrance is on the northwest side. A modern dry-stone wall has been built across its mouth.

The name Dun nan gall means fortress of the foreigners, suggesting its builders were not native to the island. 

With the sea lapping up to it, its shoreline location ideal for fishing and trade and with a fresh water stream running nearby, surrounded by good farming land, this stronghold would be a very attractive location for any new comer establishing defendable foothold on the island.

A fabulous place to explore with spectacular views across the bay.
