Bad Ischl is a spa town in Austria. It lies in the southern part of Upper Austria, at the Traun River in the centre of the Salzkammergut region. The town consists of the Katastralgemeinden Ahorn, Bad Ischl, Haiden, Jainzen, Kaltenbach, Lauffen, Lindau, Pfandl, Perneck, Reiterndorf and Rettenbach. It is connected to the village of Strobl by the river Ischl, which drains from the Wolfgangsee, and to the Traunsee, into which the stream empties. A subcamp of the Dachau concentration camp was located in the town. Besides the Kaiservilla, the city offers several health spas and tourist attractions like the historic Kongresshaus opened in 1875, the new Kurhaus built by Clemens Holzmeister in 1932 as well as the former residence of Franz Lehár, that he acquired in 1912 and today serves as a museum. The Saint Nicholas parish church was first mentioned in a 1344 deed. Bad Ischl is also known for the Konditorei Zauner pastry shop, former k.u.k. purveyor established in 1832, and the small Lehártheater built in 1827. A gondola lift runs from the town up to the Katrin alpine pasture at 1415 m (4643 ft) which offers a panoramic view of the Salzkammergut mountains. The ruins of Wildenstein Castle, that burnt down in 1715, are nearby.
