The Moorish fortress or Alcazar of Carmona rises above the Puerta de Sevilla (Gate of Seville), forming an almost impregnable defensive complex. It underwent major alterations in the 14th and 15th centuries. Theestoration work carried out between 1973 and 1975 included the refurbishing of several sections as venues for staging cultural events.
Puerta de Sevilla origin dates back to the 9th century BC. The Carthaginians created the first layout, of heavy rectangular appearance, and made it their bastion against the Romans. The Romans reinforced and restored the structure with a set of gates which is still preserved. Many interventions were carried out from the 12th century onwards.
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.
