This map is based on a water-colour of the area painted in 1834 detailing the extent of the finds to that date. It shows the position of the Theatre (1), the Basilica (2) and the Villa of the Papyri (3) relative to the open excavation site.
The detail and extent of the discoveries in the explored area is largely due to the diligence of a Swiss engineer, Karl Weber, who made the first map of the sub-terranean galleries and the buildings they led to. His methodology was continued by the Spanish architect Framcesco La Vega who produced as complete a plan of Herculaneum as was possible from the available evidence.
