The Allentown Museum collection numbers more than 17000 works of art. Holdings include decorative arts, textiles, works on paper, more than 100 European Old Master paintings and sculptures including 53 Renaissance and Baroque works from the Samuel H. Kress Foundation, as well 95 Indian and Tibetan sculptures.
Notable in the collection are Gilbert Stuart's portrait of Ann Penn Allen, granddaughter of the founder of Allentown; and the permanent installation of a library room designed by Frank Lloyd Wright.
The Museum's goal is to develop an American collection parallel to the quality of the European collection.
