Once upon a time, or the 1st century A.D., Roman Emperor Tiberius retired to the Isle of Capri, Italy, and used this beautiful Blue Grotto, a sea cave, as his personal swimming pool. Emperor Tiberius loved the Blue Grotto so much that it was his favorite nymphaeum, a temple dedicated to sea nymphs…also described as a sanctuary for water nymphs. Photo #1 by Luftphilia
