Visit Ludington tells a little about the historic Beach House at Ludington State Park.
The Beach House has a long history of weathering the changing Michigan seasons within the Ludington State Park. This landmark has now received a makeover, and it’s a real showplace for the state park system. Built by the Civilian Conservation Corps in 1935, the Lake Michigan Beach at 116 ft. long and 35 ft. wide, has been a familiar sight for visitors to Lake Michigan within the State Park.
…The Lake Michigan Beach House is unique in nature due to the fact it is the only Arts-and-Craft inspired design bathhouse found on the shores of Lake Michigan. Also of significance is the role the CCC played in its construction–from architect Ralph B. Herrick to all the CCC workers who built the Beach House from recycled brick and pressed mortar. This style has not been found at any other state park in Michigan…and it is the largest and most intact of the CCC-built structures within the Ludington State Park.
