Herculaneum was discovered in the early 18th century, at a depth of 50-60 meters below the surface.
In the 20th century, modern archaeological excavations restarted discovering completely a small part of the city, but it was found that the earlier excavations had damaged the structure of most of the surviving buildings.
Recent archaeological works at the site have uncovered one of the largest Roman houses of the time: the Villa of the Papyri.
Today the archaeological excavations of Herculaneum, along with those of Pompeii, constitute a historical and archaeological heritage invaluable and attract tourists from all over the world.
