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:
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
