In ad 79, the volcano Vesuvius erupted, burying the cities of Pompeii and Herculaneum under ash and rock, and leaving them remarkably well preserved for centuries. While Pompeii has been extensively written about and popularized, the remains of its sister city, a smaller yet wealthier community close to the sea, are less widely known, but they have yielded spectacular archaeological evidence. Illustrated with more than 300 newly taken colour photographs and archive illustrations, plus eight spectacular 360 degree panoramas, it is the definitive overview of what we know and understand about Herculaneum, of what is still unknown and mysterious, and of the potential for future discoveries in both archaeological and political contexts.
