15. Haludovo Palace Hotel, Krk, Croatia
Haludovo Palace Hotel is clearly not of our time, but it’s hard to tell exactly when it is from. The design and modular shapes feel futuristic, but the state of decay places it firmly in the past. In reality, the hotel complex was built on the island of Krk in 1971, in a style typical of Communist-era architecture (the asymmetrical concrete, the brutally modern facades) and spent a few golden decades hosting actors and world leaders visiting former Yugoslavia. When war hit in the 1990s, tourism dwindled, and the hotel hosted its last guests in 2001 before closing its doors for good. The casinos, saunas, and tennis courts have fallen into disrepair, but visitors can still appreciate the hotel’s skeletal buildings—and let’s face it, any day spent on a Croatian island is a good one.
16. Kennecott, Alaska
Nearly $200 million worth of copper was processed in Kennecott (located in Wrangell-St. Elias National Park) from 1911 to 1938, a self-contained mining town with its own hospital, skating rink, tennis court, and dairy. But most of the buildings have now been abandoned for around 60 years, some of which have deteriorated past the point of salvation—but are still quite lovely. The National Park Service acquired many of Kennecott’s buildings and lands in 1998; the visitor center is open from Memorial Day through Labor Day, and the recreation hall is available to rent for events.
