PORTLAND — Maine’s largest city is getting a new shelter for youths.

Portland’s Preble Street will host an open house on Tuesday at the newly expanded and renovated Joe Kreisler Teen Shelter. The public is welcome to tour the shelter, which is scheduled to be fully operational the first week of January.

The Joe Kreisler Teen Shelter replaces the Lighthouse Shelter, providing 24 beds for homeless teens without family, friends or resources. The shelter will ensure that teens are safe around the clock and have access to nutritious meals, adult supervision and connection and resources to help turn their lives around.

Preble Street is the leading provider of services to Portland’s homeless and low-income residents and serves more than 500 people each day.
