The original plan for the museum called for three wings, but only the west wing and central hall were completed before funds ran out. The east wing was added in 1998, restoring the neo-classical symmetry of the building's original design, and was built to match the original structure, including the brick and oolithic limestone detailing. The museum's interior includes beautiful and original oak woodwork, plaster wall ornamentation and ceramic tile floors.
