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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
