There is a clever observation platform built into a pond in Vöcklabruck, Austria. The platform, rather than being raised, is sunken into the water allowing visitors to walk below the water's surface without getting wet. Pictures of this pond, first reported by Bored Panda, and quickly picked up by other publications, are currently circling the Internet but no additional information seems to have been collected. Some readers speculate what would happen during floods, but if you notice carefully, water is already spilling over the walls into the deck. So there is likely a drainage system in place that keeps the deck water free even during floods or heavy rainfall.
