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 22.8m 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 $US130 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.
