Lowell was the first city in the United States to launch this prestigious event dedicated to preservation, architecture, and design which is presented as part of the community’s National Preservation Month activities. Each May you can explore many of Lowell’s historic buildings, from residential lofts to churches to rehabilitated mills and everything in between. Doors Open Lowell is completely FREE with no registration or tickets required.

Lowell is known nationally and internationally for its preservation-based economic development efforts. Nearly $1 billion has been invested in the Downtown Lowell Historic District with nearly 98% of 5.2 million square feet of mill space having been rehabilitated. Preservation sets the stage for much of the city’s economic development, tourism, and cultural efforts and Doors Open Lowell is an opportunity to catch a glimpse of that success.
