Of Celtic origin, Moudon experienced an important development in Roman times as a station on the transit route between Avenches and the Great St. Bernard. The medieval town was fortified and equipped with a castle. After 1219 it came under the control of the Savoy and obtained franchises in 1285. Under the Bernese from 1536, it declined in importance when the bailiffs settled in Lucens Castle.
Moudon retains its medieval character but no longer has the ancient ramparts and castle. Only the Broye tower, built in the 12th century during the brief domination of the Zähringen, has survived in the old town.
