Called the most historic street in America, Germantown Ave. in Philadelphia links Germantown, Mount Airy, and Chestnut Hill, the three neighborhoods of Philadelphia that make up the old German Township. Germantown has been the site of some of history's most significant events. Covering the period from Colonial times to the 20th century, these images tell in sharp detail the story of the region founded by German-speaking settlers in 1683. Germantown evolved into a prosperous industrial center by the mid-19th century, and became home to wealthy businessmen who built elaborate Victorian villas and gardens. The area was home to an early commuter railroad and to many factories and textile mills, which attracted European immigrants. 200+ B&W photos.
