At first glance it looks like some hotel in Belgium has sacrificed floor space for a massive four-sided novelty alarm clock to attract tourists. But in reality, what you're seeing is actually the top of a clock tower with a hotel built around it.
It's the work of Japanese artist Tazu Rous, who built the single room—surrounding the city of Ghent's train station clock tower— some 75 feet above the ground. So it offers beautiful views of the city, and the most effective morning wake-up call you'll ever experience. You can even book the room for just $130 per night, but you'll want to go light on the luggage since the temporary structure holding it up doesn't appear to include an elevator.
