Winterthur (ˈvɪntɐtuːɐ̯; lang) is a city in the canton of Zürich in northern Switzerland. With over 110,000 residents it is the country's sixth-largest city by population, and is the ninth-largest agglomeration with about 140,000 inhabitants. Located about northeast of Zürich, Winterthur is a service and high-tech industrial satellite city within Greater Zürich. The official language of Winterthur is German, but the main spoken language is the local variant of the Alemannic Swiss German dialect, Zürich German. Winterthur is usually abbreviated as Winti in the local dialect and by its inhabitants. Winterthur is connected to Germany by direct trains and has links to Zurich Airport. It is also a regional transport hub: the A1 motorway from Geneva through to St. Margrethen connects in Winterthur with the A4 motorway heading north toward Schaffhausen and the A7 motorway heading close to the Swiss-German border at Kreuzlingen. There are also roads leading to other places such as Turbenthal. The railway station is the fourth busiest railway station in Switzerland, and is 20 minutes away by train from Zürich. Vitudurum was a vicus in what is now Oberwinterthur during the Roman era (first century BC to third century AD). It was fortified into a castrum at the end of the third century, apparently in reaction to the incipient Alamannic invasion. There was an Alamannic settlement on the site in the seventh century. In a battle near Winterthur in 919, Burchard II of Swabia asserted his control over the Thurgau within the Duchy of Swabia against the claims of Rudolph II of Burgundy. The counts of Winterthur, a cadet branch of the family of the counts of Bregenz, built Kyburg castle in the tenth century. With the extinction of the counts of Winterthur in 1053, the castle passed to the counts of Dillingen. Winterthur as a city (presumably on the site of a pre-existing village) was founded by Hartmann III of Dillingen in 1180, shortly before his death in the same year. From 1180 to 1263, Winterthur was ruled by the cadet line of the House of Kyburg.
