Człuchów Castle consists of some of the defence walls and the 46-metre tower. The Człuchów stronghold was built during the 14th Century by the Teutonic Order. The exact date of completion is unknown but it is assumed to be the year 1365. During the history, the castle was considered an unconquerable fortress, and was an important element in the defence system of the monastic State. The glory days of the fortress date were up to the year 1772, when it was taken over by the Prussians, while the city fire of 1793 completed the devastation of the building. In order to rebuild the town, the residents were granted consent to deconstruct the Castle, leaving only the tower and fragments of the defence walls. A neo-gothic Evangelical church was added onto the foundations of the former Castle chapel during the years 1826-1828. This church is associated with one of the mysteries; the lost Amber Chamber, supposedly hidden by the Nazis.
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.
