Torretrencada is a Talayotic settlement (1000-700 BCE) that was occupied until the Roman conquest in 123 BCE. Several of its monuments can still be seen. They include the talayot a seriest of artificial burial caves dug out of the rocky ground and burial chambers carved in the rock, probably dating from the high medieval period. The taula is one of the most beautiful on the island, with a reinforcement pillar at the back, but all that is left of the surrounding wall is a section underneath the modern dry-stone wall. The site dates back to the post-Talayotic period (650-123 BCE) and was used by the community for performing rituals.
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.
