Serapeum, a Roman Marketplace in Pozzuoli, Italy, records deformation of Campi Flegrei caldera over two millennia. It was built above sea level about 2000 years ago, but mollusk borings on the large marble columns indicate that it subsided by 7 meters (23 feet) below sea level before being uplifted above sea level once more in the past several hundred years.
