Castello di Vezio is a castle located nearby Varenna and Perledo. Characterized in the main tower by square merlons, similar to Cly Castle in Aosta Valley, it commands the Lake Como. It was once connected by walls to the village of Varenna below.
The castle was built in the late 11th-early 12th century and was restored several times in the following centuries. In the late 19th century and in 1956 remains of tombs from the Iron Age, as well as weapons and armors were found in the area.
The Castle also had dungeons built during the First World War, as part of the so-called linea Cadorna. It currently houses gardens and a group of birds of prey, raised by a local falconer.
It became open to the public in 1999. The tower houses a permanent exhibition dedicated to Lariosaurus, an extinct sea reptile from the Middle Triassic period, which takes its name from the lake after its discover in Perledo in 1830.
References:Carlsten is a stone fortress built on the orders of King Carl X of Sweden following the Treaty of Roskilde, 1658 to protect the newly acquired province of Bohuslän from hostile attacks. The site of Marstrand was chosen because of its location and its access to an ice free port. Initially a square stone tower was constructed, but by 1680 it was reconstructed and replaced by a round shaped tower. Successive additions to the fortress were carried out, by the inmates sentenced to hard labour, until 1860 when it was reported finished. The fortress was decommissioned as a permanent defense installation in 1882, but remained in military use until the early 1990s.
The fortress was attacked and sieged twice falling into enemy hands. In 1677 it was conquered by Ulrik Frederick Gyldenløve, the Danish military commander in Norway and in 1719 by the Norwegian Vice-Admiral Tordenskjold. At both occasions the fortress was returned to Swedish control through negotiations and treaties.
