The Collegiate Church (Stiftskirche) towers over the town of Herrenberg, dominating the cityscape. It was built in two main phases of construction (1276-1293 and 1471-1493) and was the first Gothic hall church to be completed in Württemberg. In 1749 the two Gothic towers were demolished and replaced by the Baroque onion dome.
Among the church's outstanding features are the baptismal font from 1472, the stone pulpit from 1504 by Master Hanselmann and the choirstalls from the year 1517 with carvings by Heinrich Schickhardt, the grandfather of the famous architect. The high altar dating from 1519, with paintings by Jerg Ratgeb, is now to be found in the State Gallery in Stuttgart. The Stiftskirche is home to the Herrenberg Bell Museum – and it also boasts the oldest rose window in Swabia.
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.
