23. Michigan Theatre, Detroit
Built in 1926 on the spot of Henry Ford’s first workshop, the Michigan Theatre was once an opulent downtown Detroit institution with seven stories, 4,000 seats, and a construction price tag of $5 million. The theater closed its doors in 1967, following the boom of suburban movie theaters and living room televisions. Since then, the space has served several purposes until it was finally repurposed as a parking garage in the late 1970s. The cathedral ceilings and frescoed walls of the once-majestic playhouse have certainly seen better days, but it sure beats your average concrete parking structure.
24. Lake Reschen Bell Tower, South Tyrol, Italy
Beginning in 1940, Italian electric company Montecatini built a dam to unify two lakes in South Tyrol—Reschensee and Mittersee. The area was once home to several villages, but the towns were flooded (intentionally) during the dam-building process. The only visible reminder of the drowned cities is a 14th-century bell tower—sort of like Rapunzel meets the Quarter Quell. The surrounding mountains are popular among hikers, and you can even walk right up to the tower when the lake freezes over in the winter.
