Lansdowne was once a vacation resort for residents of Philadelphia. People traveled by rail and horse to relax in the borough's Victorian homes. Many of the homes have since been turned into multiple-dwelling apartments which, due to zoning law changes, is no longer an option. Lansdowne is trying to preserve the integrity of its lovely, big homes.
It is home to numerous arts organizations, including the Lansdowne Symphony Orchestra, Celebration Theater, the Lansdowne Folk Club, and the Lansdowne Arts Festival. The Farmers Market runs, rain or shine, on Saturdays from 9 am to 1 pm, between Memorial Day and Halloween.
