In celebration of the 100th anniversary of Carnegie Museum of Art’s Hall of Architecture, an exhibition surveying its installation of nearly 150 plaster architectural casts will be on view. While most of the large cast collections assembled by museums in the late 19th and early 20th centuries have been sold or dispersed, the Hall of Architecture has remained intact throughout its 100-year history and continues to impress visitors and inspire artists of all ages. The exhibition will feature architectural drawings, period photographs, and ephemera chronicling the history of Andrew Carnegie’s creation of the third largest cast collection in the world, as well as address the production of casts in the 19th century and how the Carnegie’s casts came to Pittsburgh.
