Sokolac Castle was an extremely grand building, dominated by the powerful perpendiculars of the entry tower, and the Chapel of the Holy Trinity. The entry into the burg was through a square, three-storey tower, the façades of which were relieved with lesenes linked at the top with blind arcades, making it a unique specimen in the whole of Central Europe.

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.
