Nový zámok (literally 'New Castle') is a six-floor Renaissance building with four bastions. It was constructed in 1564–1571 as a watch tower during the Ottoman wars. Because of its dominant position, it was also used as the town's live clock (exact time was announced every quarter of an hour on a trumpet).
A permanent exhibition called Anti-Turkish Wars in Slovakia is installed on four floors of the castle. The highest floor offers a panoramic view of Banská Štiavnica and its environs.

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.
