The Château de Tiffauges is also known as the château de Barbe-bleue (Bluebeard's castle) after its most famous resident, Gilles de Rais, known as Barbe-bleue. It was here that Bluebeard perpetrated his atrocities.
The castle is in the Marches (border lands) between Brittany, Poitou and Anjou and thus an important strategic point. It is positioned on a hill at the confluence of the Sèvre Nantaise and Crûme rivers, this position providing protection against assailants.
The castle was built between the 12th and 16th centuries. The notorious murderer, Gilles de Rais (1404–1440) is associated with the castle.
For a long time, the castle was abandoned and lay in ruins, the inner yard even used for a while as a football pitch by the local club, RST Tiffauges. The castle is now owned by the Conseil Général of Vendée. It hosts a series of spectacles and collections, including medieval war machines and an alchemy centre.
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.
