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:Střekov Castle (Schreckenstein) is perched atop a cliff above the River Elbe, near the city of Ústí nad Labem. It was built in 1316 for John of Luxembourg, the father of the Holy Roman Emperor Charles IV, to guard an important trade route to Germany. After changing hands several times, the castle was acquired by the Lobkowicz family in 1563. Its strategic importance led to occupations by Imperial Habsburg, Saxon, and Swedish forces during the Thirty Years' War, as well as successive sieges by Austrian and Prussian armies during the Seven Years' War.
Although Střekov Castle was heavily damaged during those conflicts and abandoned as a military installation by the end of the 18th century, the 1800s saw many poets and artists visiting the castle, drawn by a new trend of interest in romantic ruins.
