In some popular U.S. cities, such as San Francisco, the median home value is well over $1 million. But in the scenic Italian town of Sambuca, located in western Sicily, you can buy a home for one euro, or about $1.15.

Residents have fled to larger cities in recent years, and local officials have come up with a plan to sell dozens of homes for virtually nothing in the hope of repopulating and reviving the rural town. The properties range in size from about 430- to 1,610 square feet, so they're on the small side, but most come with private grotto access.
