An ancient treasure of Ibiza up the south coast from Santa Eulária des Riu, this aqueduct built by Roman settlers in the 1st century AD runs an impressive 400-plus metres (a quarter mile). Its height and width are quite a bit more modest, varying according to the terrain, up to a mere two metres (6½ feet) tall. Its main purpose, archaeologists have figured out, was not agricultural but aquacultural - to feed fish farms and holding pools near the coast. Also nearby are the ruins of a seaside farming settlement as well as a small industrial nucleus. Some of the stretches of aqueduct are in better condition than others - and another odd thing is that the Hotel Melià S'Argamassa was allowed to build virtually alongside one particular stretch - you can practically reach out and touch it from some ground-floor room patios.
