This Greek-revival style building on the edge of Old City originally housed the Franklin Institute until it was relocated to its current large space on the Benjamin Franklin Parkway. A. Atwater Kent then purchased the space to create a museum that would honor Philadelphia’s  history.
Today, Atwater Kent Museum showcases local inventions in manufacturing and technology, toys and tools from the colonial era, and local artwork. While not nearly as widely appreciated as many of the major Old City sights, this museum is a must for those who want an in-depth look at Philadelphia’s past.
A large map of the city on the floor allows you to literally walk on top of Philadelphia’s  many colorful neighborhoods, and serves as a good orientation to the city.
