Świny Castle, formerly a gord, as a stronghold existed in its location already in the 5th century - securing the Lubawecki mountain pass, the site was recorded in Cosmas' documents from 1108, where the gord is recorded as Suini in Poloniae. Possibly, soon after, the gord had been expanded into a military stronghold, at which time it was the seat of the castellans. The castle was mentioned in Pope Adrian IV's Papal bull. After the Bolków Castle was constructed, the castle began to lose its significance, this continued up to the nineteenth century, when the castle suffered severe damage due to hurricanes (1762, 1840, 1848, and 1868). The castle suffered further devastation - it was not until 1931 when the authorities had engaged in securing the castle's ruins. Currently the castle is privately owned.
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.
