In the Prehistoric settlement of the Bronze Age (3,000 BC – 1,000 BC) in Pavlopetri, Laconia, opposite of the enchanting Elafonisos, EnaliaTec successfully delivered to the Region of Peloponnese a full underwater and on land signage system of the Pavlopetri archaeological site. The system included the construction of 18 underwater signs with special anti-fooling specifications, a set of colorful floating signage buoys and an information sign on land. The Pavlopetri prehistoric settlement site that is of great archaeological importance, is accessible to swimmers from the sandy shore and now with the design of the first underwater routes with the relevant markings and underwater signs, the tour of the archeological site is allowed with a mask and a snorkel. The laying of the underwater routes and the marking took place in the framework of the European project INHERIT (funded by the Interreg Med program). Now, the visitor/snorkeler can easily identify vaulted tombs and cist graves, rooms, walls, streets, etc. inside the underwater archeological site. EnaliaTec supported this effort of the Peloponnese Region, offering a complete and functional signage system, on land and underwater, available to visitors of the archaeological site.
