The Tour Vauban (Vauban Tower), initially known as the tour de Camaret, is an 18m-high polygonal defensive tower built to a plan by Vauban on the Sillon at Camaret-sur-Mer, as part of the fortifications of the goulet de Brest. It has three levels and is flanked by walls, a guardhouse and a gun battery which can hold 11 cannons as well as a cannonball foundry added in the French Revolution period.
Drafted in 1683, the tower was designed in 1689 by Vauban and construction was supervised by the military engineer Jean-Pierre Traverse from 1693 to completion in 1696. The 11 cannons in the battery are believed to have been forged with those for the battery on pointe du Grand Gouin, for the Quélern defensive-lines and the many neighbouring batteries. In the French victory in the Battle of Camaret on 18 June 1694, the battery and its two guard houses were only armed with nine 24-pounder cannon and three mortars firing 30 cm balls.
Camaret-sur-Mer is a member of the network of major Vauban sites. Since 7 July 2008 the tour Vauban and 11 other sites have been classed as a UNESCO World Heritage Site.
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.
