on the exterior of the building, non-original italianate style decoration, such as architrave moldings, were removed. old layers of paint were also removed, and it was found that originally the brick had been painted in a red glaze with painted mortar joints; this gave the building a uniform, crisp look. a similar red glaze with white mortar joints was painted on the building during the restoration. older additions were removed from the rear of the building, and a new addition, to be part of the visitors' center, was constructed in their place.
