Leaving Langwies and Chur

Archaeological evidence of settlement in Chur goes back to 3900-3500 BC, making Chur one of the oldest settlements in Switzerland. Remains and objects from the Bronze and Iron Ages have also been found in the eastern sector of the current city's centre. The Roman Empire conquered the area that then came to be known as the Roman province of Raetia in 15 BC. In the 4th century, Chur became the seat of the first Christian bishopric north of the Alps. In the 13th century, the town had some 1,300 inhabitants and was surrounded by a line of walls. The Chur led League of the House of God allied with the Grey League and the League of the Ten Jurisdictions in 1471 to form the Three Leagues, of which the Greay League (Graubunden) survives to this day!)
Chur is home to many buildings listed as Swiss heritage sites including the old medieval city and Welschdörfli a prehistoric settlement and Roman Vicus. There are four archives or libraries; the bishop's palace (library and archive), $ the Cantonal Library, the Cantonal Archive of Graubünden and the city archive of Chur. There are four museums: the Bündner Kunstmuseum (Art Museum), Bündner Naturmuseum (Natural History Museum), the Dommuseum and the Rätisches Museum in the Haus Buol. There are three listed churches - The cathedral of the Assumption, the Catholic Church of St. Luzi and the Reformed church of St. Martin.
The first church on the cathedral site was built in the first half of the 5th century, the Romanesque crypt was probably built under Bishop Tello (758-73) and current building was built between 1154 and 1270.
The Church of St. Luzi was probably built in the 8th century.
