The medieval aqueduct of Salerno was built in the ninth century to supply water to the monastery of St. Benedict, at the eastern walls. It is located in the historic center of Salerno, under the hill Bonadies and its Arechi Castle.
It consists of two branches: one coming from the hills to the north, the other one from the high ground to the east of the city; both rejoined along the street Arce (which by their arches is named), at an edge of the old city walls. At first only stocked the Benedictine monastery, and later, a branch underground allowed to supply the convent of Piantanova, Via Mercanti.
The aqueduct was popularly renamed 'Bridges of the Devil' and it was said that it was built in a single night, with the help of demons, by the magician of the twelfth century Peter Barliario. The popular superstition considered also that venture under the arches between dusk and dawn would bring to the meeting with devils or evil spirits.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
