Archaeologists in Scotland have used new technology to uncover the underground remains of a Roman fort. According to the organization Historic Environment Scotland, they found the ruins near the town of Clydebank by using a special measuring technique that can be used to determine whether there is anything underground without having to excavate.

According to the PA news agency, an antiquarian had already pointed out a fortress in the region in 1707. In the 70's and 80's archaeologists in the same region had already searched for it, but had not been successful at the time.

"It's great to see our historical knowledge increasing as new methods give us new insights into the past," said Riona McMorrow of Historic Environment Scotland.

The site, which was once believed to have been manned by ten to twelve soldiers stationed nearby, is believed to be part of the 2nd-century Antonine Wall.

The Antonine Wall was one of the largest Roman fortifications in northern Britain and is now one of Scotland's six Unesco World Heritage Sites. The rampart is said to have once had around 40 fortresses, only nine of which have been found so far.
