Our Mission
The Preservation League of Staten Island (PLSI) works for the conservation and continued vitality of Staten Island's historic resources. The League was founded in 1977 by a group of community-minded citizens concerned about Staten Island's vanishing historic environment. We sponsor programs about the recognition, care and restoration of historic properties. We have given neighborhood and historic house tours and we confer annual awards for outstanding preservation work. Landmark designation for significant sites is a priority.
