Caerleon is the historically important site of the Roman legionary fortress of Isca Augusta. St Cadoc's Church stands over the principia (headquarters), where the legionary standards were kept and statues of the Roman emperors venerated. The earliest surviving part of the church dates back to just after the kingdom of Glywysing was overrun by the Normans during the twelfth century and is thought to be the work of Hywel ap Iowerth, who was also the founder of the Cistercian Llantarnam Abbey.
The current church is in the Perpendicular style, which was fashionable in the fifteenth century. The tower, which stands at the southwest corner of the church, has a lower stage that was probably part of the original Norman church, incorporating twelfth/thirteenth century lancet windows. The church features a series of impressive stained-glass windows depicting the life of Christ and symbolising the faith and devotion of the saints associated with Caerleon.
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.
