In 1692 the naval Battle of La Hougue took place between the English and the French close to the island of Tatihou. The so-called Vauban Tower (Tour Vauban de Tatihou) was built in 1694. In 1756 the surroundings of La Hougue were defended by many batteries and forts, but the lack of regular maintenance ensured that these quickly fell into disrepair. In 1720 Tatihou was used for quarantining plague victims from Marseilles.
Vauban Tower is part of the UNESCO World Heritage site of Vauban Fortifications around the France.
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.
