Château de Talmont was founded by the Count of Poitou in the 10th century and the first documentary records appear between 1040 and 1046. In 1138 the castle was held by Joscelin de Lezay, who was attacked by Louis VII; despite being considered invulnerable because it could be resupplied from the sea, the castle was burnt by the king. Talmont passed on to the Mauléons by the 1140s, but in 1182 Richard I of England became the lord of Talmont; he remained in control of the castle until his death in 1199, when it was returned to the Mauléon family.
The castle was enlarged during by the King Richard I of England with round towers, curtain wall and new gate. Most of the castle was demolished in the 17th century.
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.
