Built during the Renaissance period, it still has mullioned windows topped with bracketed lintels, a wooden gallery that was replaced identically during the restoration-extension of 2013 and, inside the building, a beautiful stone spiral staircase. Built against the ramparts that encircled the city, it probably belonged to Vespasian de Gribaldi, a friend of François de Sales and former archbishop of Vienne in the Dauphiné, who left his name to it. It may have been an outbuilding of his nearby manor house, located at the corner of the upper street.

The historical and iconographic archives will be digitised and accessible to all from computer stations. A valuable educational tool for research, schools and the public.
The Maison Gribaldi is open to the public during exhibitions.
