Château de la Rochette is a historic 17th-century structure built by Jacques de Sassenage at the foot of the Massif du Vercors cliffs in Fontaine, Isère. Originally a fortified house from the 15th century, it was renovated in 2011 while respecting French heritage standards and reopened in October 2012. The château overlooks Parc de la Poya and sits at the gateway to the Vercors region. Today it operates as Tempologis, offering self-catering accommodations that blend historic architecture with modern amenities, allowing guests to experience the countryside setting near Grenoble in a restored heritage property.
