La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a 'mound' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed 'passage graves', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental. Since the excavations and restoration of the original entrance of the passage observations from inside the tomb at sunrise on the spring and autumn equinox have revealed that the orientation of the passage allows the sun's rays to shine through to the chamber entering the back recess of the terminal cell. Although many passage graves showed evidence of continued activity into the Late Neolithic period, La Hougue Bie was abandoned before that time.
On top of the mound were built two medieval chapels, one from the 12th century and the other from 16th century There is also a museum today.
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.
