The Monastery of St. Simeon was established in the 7th century by Coptic monks seeking to escape to the meditative quiet of the desert. The complex was rebuilt at least once before it was finally abandoned during the 13th century; however, the monastery remains in surprisingly good shape given it long disuse.
The complex was walled to protect the monk from Bedouin raiders and other threats and the stone and mudbrick walls make for an impressive sight on approach. It engenders thoughts of a medieval fortress more than a religious institution. Inside are the remains of a church, a stable, and other buildings vital to the simple lives of these medieval monks.
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.
