Ojców Castle was part of a system of castles known as the Eagle's Nests - formerly protecting the southern border of the Kingdom of Poland. Currently it houses a museum dedicated to the castle in its renovated castle-tower. The castle was used as a stronghold, built by Casimir III the Great in the second half of the 14th century.
A legend mentions, that the caste was built by the Duke of Wrocław Wiesław I, Popiel's brother-in-law, however te first recorded information about the castle comes from the fourteenth century - linking up with King Casimir III the Great, who used the castle as part of his defensive line against the Kingdom of Bohemia and the south. The King was called the castle in honour of his father, Władysław I Łokietek, calling it Father by the Rock. In 1665 the stronghold was taken over by the Swedes, which they partially burned and deconstructed. The House of Koryciński, who owned the castle, had renovated it, and built additional living quarters. Various battles throughout the oncoming centuries had caused the castle to be shifted between different owners. Causing the castle to go through several cycles of renovation and deconstruction, currently the castle stands as the picturesque, and renovated ruin.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.
