Plan a trip to Philadelphia
Called the "New Athens" by Benjamin Franklin, Philadelphia is the nation's first capital, the place where the Declaration of Independence, the US Constitution, and the Bill of Rights were written and signed. Learn all about its rich history at Independence Hall in the Old City district, open 365 days a year. Weave your way through small streets to experience four centuries of architecture alongside new art galleries and cozy cafes. You'll still feel the original European aesthetic as you walk through the Old City historic quarter. Hear stories on a backstage tour at the Walnut Street Theater, built in 1809 and the oldest theatre in the country. In the late 17th century, William Penn organized fishermen, farmers, and hunters to sell their wares - this grew into the 80-merchant Reading Terminal Market. For live music in a small concert setting, explore Theater of the Living Arts just about any night of the week. Discover the creative design shops of the outrageous Fishtown neighborhood - open gallery nights along Frankford Avenue are free on first Fridays of the month.
