Three mica-schist stones stand side by side in Kintyre, their line drawing the eye beyond the field toward distant hills and islands. Ballochroy is a prehistoric standing-stone alignment, meaning upright stones set in a deliberate row.
Alexander Thom argued that the stones used distant landforms to mark solstice sunsets, though such astronomical interpretations should be treated carefully. Even without accepting every claim, Ballochroy remains one of the most striking megalithic groups in South Argyll.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
Ballochroy consists of three vertical stones standing side by side on the Argyll peninsula.
The stones form part of a wider South Argyll megalithic cluster.
Alexander Thom argued that the stones and distant landforms created a precise astronomical calendar for midsummer and winter solstices.
The central stone's flat face points toward Cora Bheinn on Jura.
The shortest stone points toward Beinn a' Chaolais, the southernmost of the Paps of Jura.
The smallest stone may be broken at the top.
