We promote preservation and revitalization of historic buildings, neighborhoods, and landscapes and encourage high-quality new architecture to enhance the livability and economic vitality of Portland and surrounding communities.
In addition to seasonal guided walking tours, Greater Portland Landmarks offers several self-guided walking tours. You can experience four of the tours through the interactive maps, download PDFs, or purchase a full set of Map booklets (includes Congress Street, State Street, Western Promenade and the Old Port). To further enrich your experience, review common Architectural Styles on our website to prepare for your tour.
