The Hajji Ahmed the Ducat Minter's Mosque is one of the most easily recognizable architectural symbols of Livno, Bosnia and Herzegovina. Built in 1574 (some date to 1587), it is situated on a hill overlooking old town of livno, the river Bistrica and the spring Duman in the upper section of the old town of Livno. The mosque complex consists of compact main building of the mosque under a dome and uncharacteristically short minaret, with a clock tower which was erected some 100 years later, between 1670 and 1680. but more likely in 1659. It is still in function today, and finally within perimeter is almost 500 years old necropolis with characteristic early Bosnian Muslim tombstones and later ones.
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.
