Archaeologists have discovered evidence of Roman occupation and ritual activity hidden inside a partially flooded cave in Spain. The remains date to about 1,900 years ago, researchers say.
The researchers were exploring the depths of the cave, which is located in eastern Spain, by flashlight when they noticed a rusty coin wedged between a crack in the ceiling and a stalactite, according to a translated statement. Subsequent analyses revealed that the coin dates from the time of Emperor Claudius, who ruled the Roman Empire from A.D. 41 to 54. The coin was likely put there as an offering, the researchers noted.
