Maglaj Fortress is a large castle mentioned for the first time on in 1408 in the charter of the Hungarian king Sigismund. Although it was made in 14th century to serve in the defence of the Bosnian kingdom, not until the time of the Ottoman rule did the Fortress get its final shape. Fortress Gradina was declared a national monument of Bosnia and Herzegovina in 2005.
The Fortress Gradina consists of 5 towers: Širbegova or Kapi tower, Dizdareva or Southern tower, Defender tower, The Captain's or North tower and the Clock Tower. The exact data that we posses about the construction of the Maglaj Fortress is only about the Clock tower, and all the information on the appearance, construction and dimensions of the other parts of the Fortress are currently unavailable.
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.
