Forte Sperone is the heart of Genoa's 19th-century fortifications, located right at the apex of the 'Mura Nuove' (new walls) from 1630, which to this day take the shape of mighty ramparts nestled in the hills behind the city centre.The fort's main entrance, with the Savoy coat of arms above it, is protected by a moat and a heavy gate that was once connected to a drawbridge via two chains; other important architectural elements include a well-preserved gunpowder magazine, located in the lower part of the fort, central barracks with large rooms, and a beautiful little chapel attached to the complex.
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.
