Château d'Ailly was first mentioned in 1050 when Robert d'Ailly built a manor surrounded with walls, moat and mill. The near St. Gerbold's Church was also built then. In 1431 english King Henry VI gave the land property of Ailly to his uncle. Back in French possession, the manor belonged to the Courseulles and De Saint Laurens families until it was acquired by d'Aubert de Caudémone in the 17th century. Charles d'aubert d'Ailly, a Knight of Malta, transformed the château in 1721 to the current appearance.
The archaeological project in 1832 unearthed the nine famous d'Ailly helmets, which were well-preserved helmets dated back to the end of Bronze Age.
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.
