A day of real estate weirdness

'Obscura' event features tours of unusual homes

Atlas Obscura is an online guide to wondrous, curious and bizarre sites across the globe. Its range is varied and global, and the site includes a section featuring strange and unusual homes and architecture in the U.S.

And this Saturday, March 20, is Obscura Day — a sort of global open house event for some of the extreme homes and exotic attractions around the world that are featured at the site.

In West Palm Beach, Fla., for example, you can trek through the abandoned streets of Unit 11 in the Everglades on Saturday. While this failed housing development has been uninhabited — by humans, at least — for 40 years, it has become a home for wild boars, carnivorous plants, and exotic birds living amid a suburban rectangular grid of forest.
