The Alcazar of Jerez de la Frontera is a former Moorish alcázar, now housing a park. A first fortress was probably built in the 11th century, when Jerez was part of the small kingdom of the taifa of Arcos de la Frontera, on a site settled since prehistoric times in the south-eastern corner of the city. In the 12th century, a new structure was erected to be used as both residence and fortress by the Almohad rulers of southern Spain. Later, after the Reconquista of Andalusia, it was the seat of the first Christian mayors.
Its various parts, which have been magnificently restored, include the Christianised Mosque dedicated to Santa María la Real, the Arabic Baths, the Oil Mill and the beautiful gardens.
The Dark Chamber is located in the tower of Villavicencio Palace (17th-18th centuries) in the Fortress, the oldest monument in this city. The visit includes a ticket for two exhibitions. The first one is about the dark chambers in the world. The second one is a themed exhibition about Jerez, explained by a guide who stands out the most important monuments.References:
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
