Between 1993 and 1996, several archaeological excavation campaigns at the site of Las Eretas partially unearthed the urban fabric of a fortified village from the Early Iron Age, the most significant structural remains of which included the wall and towers that defended it, and several dwellings built around a street and public square which facilitated pedestrian traffic inside the fortress.
The protohistoric village with its houses dates from the 6th to the 4th centuries BC and are typical of the Urnfield culture. Today there is a museum where thematic areas have brief text with illustrations – maps, photographs and drawings –, and a display cases showing original archaeological pieces, both from the Las Eretas site and other Navarrese Iron Age villages which have been investigated.
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.
