The Calvert County Historical Society conducted oral histories from community members during the 2021 Lower Marlboro Freedom Day.

The annual event takes you back in time to the War of 1812. British troops sailed up the Patuxent River with their sights set on Washington, D.C. during the summer of 1814. They stopped for supplies at the port of Lower Marlboro and offered freedom to local slaves in exchange for service in the British war effort.

On October 8, 2022, celebrate the men and women who won their freedom by joining us at the Historic Lower Marlboro United Methodist Church and the Lower Marlboro Hall.

Senior Naturalist Andy Brown discusses the Natural History of Barn Owls, describes the historical conservation efforts in Maryland, and outlines some future conservation goals for Barn Owls identified through the Farmland Raptor Project. His knowledge of Barn Owl natural history combined with anecdotes and stories make this a fascinating journey into the life of this secretive raptor.
