Cass Gilbert’s Palace of Fine Arts: A Visual History of the Saint Louis Art Museum Building is a digital resource providing online access to archival images and information documenting the Saint Louis Art Museum’s historic home in Forest Park.

The Saint Louis Art Museum’s building was designed by renowned American architect Cass Gilbert for the 1904 Louisiana Purchase Exposition, also known as the World’s Fair. Originally part of the Palace of Fine Arts, the Museum was the only building from the Fair designed to be a permanent structure, the "one material monument of the Exposition." It stands as a reminder of that defining event in the history of the city of St. Louis and the State of Missouri.
