Germantown is a neighborhood in the northwest section of the city of Philadelphia, Pennsylvania, United States, about 7–8 miles northwest from the center of the city. The neighborhood is rich in historic sites and buildings from the colonial era, a few of which are open to the public.
Germantown stretches for about two miles along Germantown Avenue northwest from Windrim and Roberts Avenues. The boundaries of Germantown borough at the time it was absorbed into the city of Philadelphia were Wissahickon Avenue, Roberts Avenue, Wister Street, Stenton Avenue and Washington Lane. Today, the next neighborhood to the northwest, Mount Airy, starts around Johnson Street, although there is no universally recognized exact boundary. Nicetown lies to the south and Logan, Ogontz, and West Oak Lane lie to the east.
Germantown was founded by German settlers, thirteen Quaker and Mennonite families from Krefeld (Germany), in 1681. Today the founding day of Germantown on October 6, 1683, is remembered as German-American Day, a holiday in the United States, observed annually on October 6.
