If you build a new Metro line in Rome, you have to worry about more than just engineering. Perhaps unsurprisingly, the construction team working on the Metro C, which will run through the centre of the city, has now unearthed a huge suite of ancient barracks.
The Associated Press reports that the ancient Roman ruins date back to the reign of Emperor Hadrian, in the second century AD. The buildings are thought to be the barracks for the Roman Praetorian guards, and the site could cover as much as 10,000 square feet (930 square metres). One of the uncovered sections includes a 100-metre-long hallway with 39 rooms. It looks pretty, but it’s certainly going to put a dent on the opening date of the new line. Expect delays.
