Winterthur is a city in the canton of Zurich in Switzerland. In the local dialect and by its inhabitants, it is usually abbreviated to Winti. Today Winterthur is a service centre, but many people make use of its proximity to Zurich, which is only 20 minutes by train. The city is located in a basin south and east of the Töss river. The Eulach, a little river, flows in the middle by the city, because of this the town is called "Eulach-City". Zurich lies southwest of Winterthur. During Roman times the city was known as Vitudurum. The counts of Kyburg founded the city in 1175. The charter included extensive privileges for the town. In 1264 the Habsburg family inherited Winterthur. They sold it to the city of Zurich in 1467. The church of St. Laurenz in the city centre dates from 1264, the town hall was built in 1781, the assembly hall in 1865. The city hall Stadthaus, in which the concerts of the Musikkollegium take place, was built by Gottfried Semper.
