Altdorf (sometimes written as Altdorf UR in order to distinguish it from the other "Altdorfs"; German for "old village") is a historic town and municipality in Switzerland. It is the capital of the Swiss canton of Uri. It is also the junction towards to the two passes Saint Gotthard to the south, a major north–south axis through the Alps, and the Klausen Pass to the east. Altdorf sits on the Gotthard line and is the last railway station before the entrance into the new Gotthard Base Tunnel, the world's longest railway tunnel.
