The Westinghouse Air Brake Company General Office Building (1889-1890, reconstructed 1896), designed by Frederick J. Osterling and now listed on the National Register of Historic Places, is Wilmerding's most prominent historic structure. It is a three-story brick building with limestone trim. The front facade features large openings with marbleized wood panels and terra cotta decoration. This historic building is now used as a bank office building. It was reported as being for sale in 2009 for $1.5 million. There are also two other buildings on this list that are not banks but they are still important landmarks in Wilmerding: The John Heinz Center and The Wilmerding School. The John Heinz Center is an arts center located on South Main Street that hosts various performances throughout the year. The Wilmerding School is a private school that has grades K-8. It is located just south of Wilmerding near the borough of Upper Darby. People come from all over the world to visit The John Heinz Center because it is such an amazing place full of art exhibitions and concerts. If you're one of these people then you know how valuable your time is and therefore should only spend money on things that are worth it.
