1. Osaka Maritime Museum, Japan’s Suminoe-ku
Place: Suminoe-ku, Osaka Bay, Japan
Year: 2000
Price: $93 million
The Osaka Maritime Museum, which explored the history and culture of the city, was housed in this enormous, domed building for over ten years. There was an underwater tube that led to the weather-resistant, award-winning building. A full-size model of an Edo merchant ship was the main draw.

Due to dwindling museum attendance and a lack of finance, this French-designed edifice is currently vacant and abandoned. It is unfortunate for Japanese maritime lovers that residents and visitors cannot enter the museum, but they may still view the dome from the Bay.
