Castrojeriz village is considered one of the landmarks of historic interest in the Camino de Santiago. Its rich history may take up consideration as castro Visigoth, or perhaps, also, Roman fort, (they say was founded by Julius Caesar) in whose castle was developed important battles between Christians and Moors.
The first mention of this castle dates from the 9th century during the skirmishes with the Muslim forces. There are three clearly differentiated sections: the Roman part which is today reduced to an almost hidden square tower; the Visigoth part comprising the extension to the castle with different masonry work from in the Roman part; and the medieval part.
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.
