In 1773, after the house in which Wolfgang Amadeus Mozart had been born became too small, the entire Mozart family moved across the river to the Tanzmeisterhaus on the square then known as Hannibalplatz. The building now accommodates a museum showing the various stations of the lives of the Mozart family. The building is now commonly known as Mozarts Wohnhaus and no-one knows where Hannibalplatz is as its latter-day name is Markartplatz. The existence of the building was first documented in 1617.
On the 16th October 1944 two thirds of the house were destroyed in an air raid. The owner at the time sold the bombed section of the building to Assicurazioni Generali, who then erected an office building subsequently purchased by the International Mozarteum Foundation in 1989. The International Mozarteum Foundation had already acquired the surviving section of the Tanzmeistersaal hall for museum purposes in 1955. On the 2nd May 1994 the office building was demolished and on the 4th May reconstruction of the original house was commenced according to old structural plans. In 1996 Mozart’s Wohnhaus was reopened.
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.
