The Lake Improvement Association has launched an initiative to preserve the Northwood Lighthouse, located on the north bank of Grand Lake St. Marys partway between St. Marys and Celina.

Originally built in the early 1920’s as part of the Northwood development, the lighthouse was the first to shine on Grand Lake St. Marys and stands as a testament to our rich heritage nearly 100 years later.

The LIA Northwood Lighthouse preservation project will include electrical upgrades, structural repair and shoreline protection to help the lighthouse shine bright for another 100 years.

Below, you’ll find images and text that document the history of the Northwood Lighthouse and development. Please feel free to share your favorite lighthouse photos with us at
