I'm awed and wowed by the huge number of incredible places that people have been adding to the Atlas Obscura over the last couple days. It's especially neat to see folks contributing the sorts of local curiosities that are not only not listed in conventional travel guides, but are barely mentioned anywhere else on the web. Like this odd tree in Grana, Italy, submitted by a user named Alpha:

A very unusual tree grows in the town of Grana, Italy–or rather, an unusual pair of trees. It consists of a fruit tree growing on top of a common willow tree, creating a kind of two-tiered, two-species hybrid duplex. While it's not uncommon for a small tree to grow on a larger one, it is rare to see two fully grown trees in such an unusual configuration. Nonetheless, the arrangement appears to be working well for both individuals, as the fruit tree on top bears lovely white flowers.
