Doors Open Lowell is presented annually by the Lowell Historic Board, Lowell National Historical Park, Lowell Heritage Partnership, City of Lowell, Cultural Organization of Lowell, and the Greater Merrimack Valley Convention & Visitors Bureau.

Doors Open Lowell would not be possible without the support of many dedicated people.  On behalf of those who enjoy the event, we would like to extend a special thank you.  And of course the event would not be possible without the support and access provided by the many owners and tenants who graciously open their buildings to the public.
