During a construction work near Edinburgh, UK  remains of an extremely old house have been found. The house has a large oval pit, and remains of more than 1,000 of  old tools and arrowheads.

Big quantities of burnt hazelnut shells were also found  suggesting whoever lived there roasted the nuts for food.

Archaeologists believe that the house could be more than 10,000 years old possibly belonging to the Mesolithic period.
