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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
