[In-person tour] The original 1910 McKim, Mead & White designed Penn Station is long gone, razed in 1963. But right across 8th Avenue, you can still visit the old Farley Post Office, designed by the same architectural firm to complement the grand Beaux Art train station. Sitting above the Penn Station train tracks, the Post Office was once heralded as the world’s largest mail facility. After years of scaled-back postal operations, the two-city-block building has been transformed and repurposed as the new Moynihan Train Hall. Take this adaptive reuse tour with Ginny Poleman to see the old grand Post Office lobby, remnants of the old Pennsylvania Station underground, and the new, the Moynihan Train Hall, including public art installations.
