Valeggio Castle, situated on tall spurs overlooking the River Mincio, bears the typical characteristics of a Della Scala castle, even if it was most probably built on a pre-existing structure. The Scaligeri family realised its strategic importance and erected a castle featuring the typical massive walls, square towers, battlemented keep, draw-bridge and passage guarded by a tower which is shorter than the others. The castle, built in the 13th and 14h centuries, was in full use until 1500, after which it was abandoned once it had lost its strategic importance.
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.
