Kufstein fortress is one of the most impressive medieval constructions in Tyrol. It is located on a hill rising above the city of Kufstein. This fortress has already been built very early in order to control the entrance from the Alpine foothills into the Inntal valley. However, it has been mentioned for the first time in 1205 AD, when it was in possession of the bishops of Regensburg. In 1415 it was reinforced by Louis VII, Duke of Bavaria.
In 1504 the city and the fortress were besieged and conquered by Emperor Maximilian I. Maximilian had the massive round tower built between 1518 and 1522, substantially adding to its defensibility. From 1703 to 1805 it was a Bavarian possession, returning to Austria in 1814. The fortress acted as prison for a number of political dissidents during the Austro-Hungarian empire.
Today it houses the City Museum of Kufstein. Part of it is also used for concerts and meetings.
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.
