Castello dell’Innominato ('the unnamed castle') history dates back to the Carolingian period. At that time on the hill of Somasca, the upper district of Vercurago, there was a signalling tower, that became a fortress some centuries later (documented in 1158). From 1454 this land felt into the clutches of the Republic of Venice and the Adda River became the natural border between the Serenissima (Venice) and the duchy of Milan.The fortress was destroyed by the French, who begun some months before a war against Venice and the bailey was shelled by the Russian in 1799 during the battle between the Napoleonic troops and the Austro-Russian.
today the stone arch, small chapel and walls remain. From the bailey you can admire the wonderful landscapes and sights on the eastern branch of Lake Como to the Alps (north) and the flow of the Adda River (south).
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.
