Menorca’s history, like that of all the Balearics, reaches back into prehistory, as is evidenced by the extraordinary number of well-preserved religious megaliths on the island. Bronze Age Celts erected megalithic monuments as complex as Stonehedge. More than 100 stone burial sites, altars and astronomical observatories are scattered across the southern coast. The best example is on a back road just beyond Binicalaf. You’ll see signs for it. Because of these wonderful ancient sites, you may have the feeling of being in an open-air archaeological museum while driving along the southern coast of the island.
