A well-preserved spa or bath in the ancient city of Pompei, Italy. You can't help but put yourself in the shoes of those who lived in Pompeii at the time nearby Mt. Vesuvius erupted and buried the city in some 30 feet of volcanic ash. Constantly under archaeological excavation, this image shows some of the typical architecture being unearthed by researchers. Residents of ancient Pompeii had no idea they were living next to an active volcano, according to historians.
