Penn Museum

There are a lot of museums in Philly, from ones that house really old art to ones that house really old jars containing medically-interesting body parts, but the Penn Museum is the nicest one to hang out at in the summertime. In addition to the galleries full of statues and other artifacts, there’s a garden out front with a reflecting pool and some umbrella-covered tables that you can bring your own lunch to from Han Dynasty down the street.
