Philadelphia Architecture Hike 12 of 13: Best of Modernist Style

2.5-3.5 hours, 3-4 miles, brisk pace between stops, best examples of Modernist architecture in Philadelphia, lunch afterward if there's interest. Modernist architecture is polarizing. This is especially true in Philadelphia, where from about 1940 to 1970 Modernist buildings were frequently plopped among Colonial-era buildings that are 200 years older. Whether you love or loathe Modernist architecture, I think you'll like this hike. We'll visit Philadelphia's most interesting and visually appealing Modernist buildings. Whatever your opinion going in, my hope is that you'll appreciate the style a bit more by the end of the hike. Among our first stops will be the former Rohm and Haas building, which is just a block from Independence Hall, but probably won't be mistaken for Independence Hall because it features more than 73,000 square feet of Plexiglas (Independence Hall features 0 square feet of Plexiglas . . . as far as I know). Afterward we'll wind through the Society Hill neighborhood, which - despite its age and reputation - contains several interesting Modernist buildings. Then we'll head west on Market Street to admire a series of Modernist office buildings that should get more love than they do, including the first International Style skyscraper to be constructed in the US . . . take that, New York! We will move quickly between locations, while stopping for enough time to enjoy and discuss each one. As always, no knowledge of architecture is needed . . .
