Baden is a spa town in the Austrian state of Lower Austria and the capital of the Baden district. Located about 26 kilometres south of Vienna, frequently the name is given as Baden bei Wien (Baden near Vienna); this name, however, is not official, but can be used to distinguish it from other cities of the same name such as Baden-Baden or Baden, Switzerland. The municipality consists of the Katastralgemeinden Baden, Braiten, Gamingerhof, Leesdorf, Mitterberg, Rauhenstein and Weikersdorf.
Baden is situated at the mouth of the romantic Helenental, part of the Schwechat river valley within the Wienerwald mountain range, and used to be the principal summer resort of the wealthy inhabitants of Vienna, the neighbouring Austrian capital. It possesses a Kurhaus, fifteen bathing-establishments, a parish church in late Gothic style, and a town-hall, which contains archives. The warm baths, which gave name to the town, are thirteen in number. They rise for the most part at the foot of the Calvarienberg (1070 ft), which is composed of dolomitic limestone, and are mostly used for bathing purposes. Baden is surrounded by about 120 vineyards and has about 70 wine pubs (Heurigen).
