Built in 1905-1906 for Henri Gangloff, based on plans by Louis Schwartz, its facade is decorated with an allegory recalling its original function as an art gallery, bookshop and antique shop attributed to the sculpture Bartholdi (a native of Colmar and creator of the Statue of Liberty). Acquired by the Schlumpf brothers, famous industrialists from Mulhouse who were at the origin of the automobile collection of the same name, it was transformed into a hotel in 1920.
