Milengrad was built during the reign of Hungarian–Croatian King Béla IV after the Mongol invasion of 1241–1242. Around 1303, King Charles Robert donated the fortress to the Cseszneky family in compensation for their loss of Ipolyvisk Castle. The counts Cseszneky sold it soon to Ban Mikcs, who, in 1309, ceded the lordship to the Herkffy family. In 1536, by the marriage between Katalin Herkffy and Miklós Patačić, Milengrad became the two families' shared property. In the 17th century, the Herkffy family became extinct, and the Patačićs followed in the 19th century. Due to the constant warfare with the Ottomans, and probably as well to an earthquake, by the late 17th century several walls of Milengrad fell down, and in 1683 it was already mentioned as arx diruta, a castle in ruins.
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.
