No Atomic Blast. Fire Melted the Stones of Iron Age Forts Say Investigators
In Scotland, archaeologists believe that they have solved the mystery of an Iron Age fort in which stones had melted in a process termed vitrification. The team of experts studied the vitrified fort, known as Dun Deardail, in the Highlands, near Ben Nevis and have concluded that they can explain how its stones became molten and melted.
Vitrified Forts
Dun Deardail has been dated to have been built around 500 BC, based on carbon testing. It was occupied by the Celts and later by the fierce Picts who used it as a fortress. The outline of the original fort can still be seen today as grassy embankments and it sits a-top a hill, that once had strategic significance in the area. It is perhaps one of the best known of the vitrified forts in Scotland, along with Ord Hill, and has fascinated people for centuries. Many people visit the spectacular site set in stunning landscape every year.
