Fairy Post Office

 In 2013 the sweetest post office was installed in a tree at California's Tilden Park. The original office consisted of a miniature mailbox in front of a pint-sized office complete with desk, lamp, a thimble-sized birdcage, and art on the wall. The creators of the post office put little letters in the mailbox and after a couple of months simply left the whole thing to exist in secret. When they returned months later they found that hikers who had stumbled upon post office had added decorations, like miniature wall maps and trinkets on the desk; new notes had been written and left in the mailbox. The post office even distributes its own newspaper ("The Small Times")
