The remains of what is believed to be one of Scotland's earliest homes have been uncovered during construction works.
The ancient dwelling was discovered during archaeological excavation works in a field at Echline in South Queensferry in preparation for the building of the Forth Replacement Crossing.
A large oval pit nearly seven metres in length is all that remains of the dwelling that has been dated to the Mesolithic period, around 10,252 years ago.
It has been recorded as one of the earliest houses in Scotland.
Rod McCullagh, a senior archaeologist at Historic Scotland, said: "This discovery and, especially, the information from the laboratory analyses adds valuable information to our understanding of a small but growing list of buildings erected by Scotland's first settlers after the last glaciation, 10,000 year ago.
