The last remnant of the Larkin Administration Building is this 20-foot (6 m) brick and sandstone exterior wall. Built in 1906 for the Larkin Soap Company, the Administration Building was the most majestic Frank Lloyd Wright building in Buffalo and the prototypical adaptation of his favored Prairie Style to a large office building. After the Larkin Company's bankruptcy in 1943, the Administration Building was left abandoned and decaying, and was eventually purchased by a trucking company who demolished it in 1950 to make room for a parking lot. The wall was restored in 2003; adjacent to it is an interpretive plaque with information on Larkin Company history and Frank Lloyd Wright's architectural legacy in Buffalo.
