The Chapel of St. Mary and St. Nathalan is a ruined chapel overlooking the North Sea immediately north of Stonehaven, in the Mearns of Scotland, along the northern shoreline of Stonehaven Bay. (Watt, 1985) The founding of this Christian place of worship is associated with St. Nathalan. who lived circa 650 AD. The structure is alternatively known as Cowie Chapel. The chapel is at the point where the Highland Boundary Fault meets the sea and so is on the dividing line between the highlands and lowlands of Scotland.
