Doors Open Lowell offers an insiders look into many of Lowell’s magnificent historic buildings. Being presented for the 19th time, Doors Open Lowell is the community’s signature preservation, architecture, and design event, the first of its kind in the United States when it debuted in 2002.

This free annual event held during National Preservation Month celebrates Lowell’s architectural heritage, urban living, and culture that makes the community a creative and exciting place to live, work, and visit.

So put on your good walking shoes, grab a camera, and invite some family and friends along as you discover a different side of Lowell…the inside!
