Grodno Castle (formerly Kynsburg) is a castle located in the southern parts of the Wałbrzych Mountains, on the Choina Mountain (450 metres), standing to the left of the river Bystryca. The valley of this river, formerly known as the Silesian Valley, creates a natural boundary between the Owl Mountains and to the west of it the Wałbrzych Mountains. The castle is located in Zagórze Śląskie (11 km east of Wałbrzych), Lower Silesian Voivodeship in Poland.
The picturesque location of the castle is exacerbated by the barraged Lubachowskie Lake in the foothills of the mountain.
According to tradition the castle was built in 1193, by Duke Boleslaw I the Tall. The castle, together with a network of fortresses was used as a defense line between the Duchy of Jawor and the Kingdom of Bohemia. In the sixteenth century Grodno Castle was expanded by a gatehouse, on which there is precious sgraffito, and a sundial clock from 1716. The castle was devastated in battles against the Swedes during the Thirty Years' War, slowly falling into ruins. In the nineteenth century the tower had collapsed. The last owner of Grodno, was the Zedlits family, which had continued renovation works and strengthened the castle

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.
