Tolsta Chaolais (also Tolastadh Chaolais, Tolstadh a' Chaolais) is a village on the Isle of Lewis, Scotland. It consists of about forty houses, clustered around Loch a' Bhaile, about 1round=0.5NaNround=0.5 from the A858 road between Callanish and Carloway. The name has a Norse element, Tolsta, combined with a Gaelic element, Caolas, and means "Farm by the Strait".[1] Tolsta Chaolais is in the parish of Uig,[2] and has a building as a place of worship for all denominations.
In 1979 the village was photographed by Fay Godwin as part of a landscape photography project funded by the Arts Council of Great Britain. One of Godwin's photographs of Tolsta Chaolais was published in her 1985 book of rural landscapes, Land.[3]
In 2013, the village was the location of much of the filming for the CBeebies children's television programme Katie Morag.[4]
