An inn constructed on a building burned down by government soldiers hunting Bonnie Prince Charlie is using renewable power.
Lochaber's Glenuig Inn has been fitted with solar panels to heat water and makes greater use of daylight to illuminate rooms.
Heat generated from cooling equipment is also recycled.
The inn has built up around the shell of the original building which was burned down in 1746.
Highlands and Island Enterprise (HIE) awarded £180,000 towards the refurbishment.
Inn boss Steve Macfarlane said the revamp was ambitious.
He said: "The original stonework of the main building bears the marks of a remarkable history.
"It still stands from 1746 when the English soldiers chasing Bonnie Prince Charlie, who escaped their pursuit from nearby Loch Nan Uamh, burnt it out, destroying its thatched roof and leaving only its outer shell which has been used through the generations since.
"It was right that we should preserve its place in local history and we have made a feature of the original stonework inside the inn."
