Straddling the River Drau and connected by several bridges, Villach's old town center is one of the most picturesque in southern Austria.

 A good place to begin exploring is the long Main Square (Hauptplatz), which cuts across the middle of the old town and is linked by the main bridge over the Drau at its northern end with the parish church at its southern end. 

The Trinity Column from 1739 stands in the middle of the square, which also boasts a number of fine old merchant's homes, some with attractive old courtyards. Among the most interesting are the Alte Post and the 16th-century Paracelsus Hof.
