One of the most prominent estates in Philadelphia, PA, this castle-like residence combines the modern with the romantic imagery of the medieval and has an asking price of $30,000,000. Designed by legendary architect Rafael Vinoly, famous for the Philadelphia’s Kimmel Center and NYU’s Abu Dahbi campus, this estate includes a touch of old world grandeur, with a two-story entrance hall, a living room with a 30-foot ceiling, a private tower office, and two guest houses that are designed to look like stone farmhouses.
