Château Borel is an early 20th-century château located in Saint-Egrève, Isère, in the Auvergne-Rhône-Alpes region. Built in 1903 by architects Morard and Bonnat on behalf of Charles Borel, director of a cement works, the château replaced a former medieval stronghouse. The building features refined Art Nouveau-style decorations including mosaics, stained glass, and woodwork reminiscent of 17th-century Italian palaces. Three exhibition rooms showcase restored ceilings painted by Louis Bardey and intricate wall paneling and joinery. Acquired by the municipality in 1937 to serve as town hall, the château now houses archived documents and cultural exhibits, representing an important example of early 20th-century architectural heritage in the region.
