Uncovering the Globe's Priciest Ghost Towns
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.

2. Baron Empain Palace, Egypt's El-Montaza
Place: Egypt's El-Montaza Year: 1911 Price: $10.9 million in 2020 Belgian businessman Edward Empain created this unusual, historic mansion. Empain chose to construct the Empain Palace in 1911 because he was an ardent traveler and had a deep affection for Egypt. It was not his sole scheme. In addition, the Baron proposed the name "Heliopolis" (City of the Sun) for his new city that he intended to build in the middle of the desert.
