Zrin Castle was first mentioned in the 13th century as a fortress ruled by the Babonić clan. Between 1328 and 1347, it was possessed by the members of Iločki family. In 1347, King Louis I the Great bestowed the fortress to the noble Šubić family who then changed their family name after it, becoming the Zrinski. It remained in their possession until the Ottoman invasion and conquest of the region, which led to the fortress falling to them on 20 October 1577. It wasn't until 1718 that the castle was retaken from the Ottomans.

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.
