The Tumulus of Bougon is a group of five Neolithic barrows located in Bougon, near La-Mothe-Saint-Héray, between Exoudun and Pamproux in Nouvelle-Aquitaine, France.
Their discovery in 1840 raised great scientific interest. To protect the monuments, the site was acquired by the department of Deux-Sèvres in 1873. Excavations resumed in the late 1960s. The oldest structures of this prehistoric monument, called E1 and F0 date to 4800 BC.
The Bougon Museum, opened in 1993, is a modern structure, incorporating an ancient farmhouse. The exhibition is focused on prehistory in general and the Neolithic in particular. It includes the excavated material from the site, but also replicas of a room in the Neolithic settlement of Çatalhöyük (Turkey) and of the passage tomb art from Gavrinis (Brittany). The museum also has an outside area with displays of experimental archaeology, including reconstructions concerned with prehistoric methods for the transport and construction of megalithic monuments.
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.
