Maybe we don't use them as much in the age of online maps, but atlases are handy books to have.
They show you the world. A different kind of atlas, Atlas Obscura, shows you the unique and unusual places and features of the world.
Atlas Obscura is a collaborative online project, and it has just published a book version containing some of the highlights.
From the upside-down house of Poland to the body of St. Francis Xavier in India, there's plenty to see in the book.
