Join the Fairmount Park Conservancy and Michael Burch (science educator, community organizer, and founder of the Parkside Journal) for a 2.5-mile walking tour of the Parkside neighborhood.

Parkside. The name says it all – it’s the neighborhood beside West Fairmount Park. Similarly to Strawberry Mansion on the other side of the Schuylkill, Parkside is where the city grid meets the greenspace, buffered by a boulevard of grand homes facing the park. Much of the Parkside neighborhood was built during the 1876 Centennial Exhibition. Originally populated by German-Americans and Jewish immigrants of Russian descent, after World War II, the Great Migration coupled with ‘white flight’ transformed Parkside into a predominantly African-American neighborhood, which it remains to this day. In 1983, community organizers had the neighborhood listed on the National Register of Historic Places because of its cultural legacy and many fine examples of Victorian architecture.
