The Musée des Blindés is a tank museum located in Saumur and one of the world's largest tank museums. The museum has the world's largest collection of armoured fighting vehicles and contains well over 880 vehicles, although the British Bovington Tank Museum has a larger number of tanks. Less than a quarter can be exhibited due to space limitations despite the move to a much larger building in 1993.
Over 200 of the vehicles are fully functional, in the past often performing in the annual cavalry show, the Carrousel. Saumur has been the traditional training centre for cavalry and holds the current Armoured Cavalry Branch Training School. The museum has its origins in the study collection. It's still a State institution, run by the Army. There is also a separate cavalry museum at Saumur.
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.
