The Dolmen de Soto is a Neolithic subterranean structure in Trigueros, Andalucía. It is estimated it was built between 4,500 and 5,000 years ago and is one of about 200 neolithic ritual-burial sites in the province of Huelva.
On the surface it resembles a circle-like mound with a diameter of 75 metres. It has a V-shaped passage 20.9 metres long. In the eastern end of the passage there is a chamber. During the equinox, the first sun lights the interior of the passage and the chamber for some minutes, and it is assumed this was to denote an eventual re-birth of the buried. Several of the standing-stones have engravings, and it is viewed as one of the largest dolmens in Spain. The passage has 31 standing-stones in the northern part of the passage and 33 in the southern part. The standing stones are of quartzite, sandstone, and limestone and carry 20 capstones that make the roof of the passage.
Each of the discovered eight buried bodies were in fetal position and had their respective artifacts beside them. Daggers, cups, and marine fossils were discovered. The artifacts found were not as abundant as those found in other sites; therefore, it is assumed that the Dolmen de Soto was not used for a long time. Engravings were found on 43 standing stones and describe humans, cups, knives, and geometric forms such as simple lines or circles.
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.
