Gentilhaus, Art museum and historic site in Aschaffenburg, Germany

Gentilhaus is an art museum and historic building in Aschaffenburg that displays paintings and sculptures across several floors. A central staircase connects the gallery spaces and provides access to the artworks arranged throughout the house.

Anton Gentil, an Aschaffenburg industrialist, collected art for around fifty years, acquiring nearly 2,000 objects. When his villa at Lindenallee 26 could no longer hold the collection, he bought the plot opposite at Grünewaldstraße 20 and had a house built solely for art in 1923/24, furnishing its interior himself. Sculptor and painter Ludwig Eberle, his friend, contributed designs and works to the interior.

The house takes its name from Anton Gentil, the industrialist who assembled the collection on display. Visitors can see how a wealthy person of the early 1900s chose and arranged artworks to reflect his own tastes and interests.

The house at Grünewaldstraße 20 can be visited only on organised guided tours, so arrange a visit in advance. Part of Gentil's collection is shown separately at the city's church museum under the name "From the Gentil Collection".

Anton Gentil designed all 22 ceiling and wall lamps himself, welding heavy pendant fixtures from pierced metal plates and rings that cast patterned shadows through the rooms. He also had a Welte-Mignon Philharmonic organ of type III–IV installed in 1929, with 520 pipes hidden at mid-height of the hall and no visible organ facade.
