Thank you to everyone who made the return of Doors Open Lowell a great success! Special thanks to our sponsors and of course the event would not be possible without the support and access provided by the building owners and tenants who graciously open their buildings to the public.

See you in 2025!

See a Different Side of Lowell. The Inside.

Have you ever walked by a building and wished you could see what was inside?

Now you can!

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!
