La Sergenté is a Neolithic (4500 - 3250BC) passage grave leading into a circular chamber of diameter of 3.3m. The chamber walls are of dry stone construction and stand to a height of 75cm but originally would have risen to about 1.5m forming a vaulted roof. The fallen remains of this roof were found during excavtion in 1923. The chamber was paved with flat granite slabs except for a small partitioned off area on the west side.Parts of four, round bottomed, early Neolithic bowls, a few flint chips and fragments of charcoal were recovered during excavation. Though the style is unique to the Channel Islands this simple tomb is very similar to examples found in Brittany and Normandy.
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.
