Deepest mailbox of the world

19m (63ft) unter sea level – probably the deepest mailbox in the world. The diving center Kreidesee offers to send postcards, which can be sent from this mailbox. For this purpose, waterproof postcards can be purchased in the diving center. The mailbox is emptied weekly and the cards are stamped and sent.
