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:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
