Chunks of stone fell off parts of Rome’s Aurelian walls on Tuesday, closing down a major street in the Italian capital.
The ancient city of Rome was once contained by the 10-metre Servian Wall which was built in the early 4th century B.C. When barbarian tribes invaded the city during the Third century A.D. the Aurelian walls were built to provide additional protection.
The walls, built between 271 and 275 AD during the reign of emperor Aurelian, once surrounded the capital’s seven hills and ran for 19 kilometres.
They were considered a valuable defensive measure for the city until the late 19th century.
