Do not pass "Go," go directly to Kaleva and check out the Bottle House.
"Finnish native John Makinen Sr. moved to northwestern Michigan in 1903, establishing the Northwestern Bottling Works Company in Kaleva...
The inventive and thrifty Finn also had plenty of empty bottles on hand, and found that bottle wall construction and its thick walls provided plenty of insulation. Bottle houses stay warmer in winter and cooler in summer. They are also solid and fire resistant.
Makinen used over 60,000 bottles, many of them from his own plant, to build a new family home in 1941. Workers laid bottles on their sides with the bottoms facing out toward the exterior and placed different colored bottles to form decorative patterns.
Makinen died in 1942 just before his family planned to move into the house, but his bottle house lives on today as a museum. The Kaleva Historical Society purchased the house in 1980, remodeling it and opening it as the Kaleva Historical Museum.
The Kaleva Bottle House is on the National Historic Register and the Michigan Register of Historical Places." From.
