The feudal castle of Tullins, located in Isère, today consists of the ruins of an ancient 12th-century fortress overlooking the old town. Built in the 12th century as a stronghold of the princes of the Dauphiné. Several families succeeded each other at its head, then it was leased in 1428 by the future king Louis XI. The de Clermont-Tonnerre family obtained it in perpetuity in 1650. A fire ravaged the site in 1740. A round tower from the 12th century (with openings and windows modified in the 15th and 16th centuries) remains, as well as fragments of walls.
