Located between the Black Forest and the Swabian Alps, Rottweil has about 25,000 inhabitants. The old city is famous for its medieval center and for its traditional carnival, (called "Fasnet" in the local Swabian dialect). The oldest town in Baden-Württemberg,  its appearance has changed very little from the 16th century.
In 1463 the city joined the Swiss Confederacy, with which it was closely aligned for several centuries. Both its status as free city and its alliance with the Swiss Confederacy were eventually lost with the conquest of the region by Napoleon in 1803.
The late-Romanesque and Gothic-era Münster Heiliges Kreuz ("Minster of the Holy Cross"), built over a pre-existing church from 1270. It features a crucifix by Veit Stoss and noteworthy Gothic sculptures.
Kapellenkirche (1330–40), a Gothic church with a tower and with three statue-decorated portals.

The City museum, including a notable Roman mosaic with the legend of Orpheus.
The late-Gothic Town Hall (1521).
