I recently attended a short course at the Wharton School of Business so I had a chance to look at the campus grounds and buildings. It is a great space to wander around and enjoy something very different to the gritty streets of downtown Philly.
The trees, lawns and gardens make for a quiet, calm hideaway. Lovely walks through a range of buildings and architechure dotted with art installations and statues. Take some time out it is worth it.
And of course, being a university, it has easy access to great pubs and eateries that are fun and good value. My pick was Sansom Street where there is plenty to choose from.
