Archaeologists have unearthed the ruins of a Roman fortress in Germany that once protected against barbarian intruders.
For more than a century, historians have suspected that a defense structure known as a castrum was lurking beneath a cobblestone street in Aachen, a city in western Germany. However, it wasn't until recent excavations ahead of a construction project that archaeologists finally saw the remains of the 1,700-year-old fortification. They immediately knew it was a Roman construction, according to a translated statement.
