On the About Us page, the Atlas Obscura team says, “if you’re looking for miniature cities, glass flowers, books bound in human skin, gigantic flaming holes in the ground, bone churches, balancing pagodas, or homes built entirely out of paper, the Atlas Obscura is where you’ll find them.”
Founded in 2009, Atlas Obscura is a collaborative website documenting unusual and interesting places around the world. You’ll learn about architecture, museums, and natural wonders. Search by continent, country, or even state. There are dozens of curious sites right here in Philadelphia! Also explore by categories such as martian landscapes, strange science, or eccentric homes.
