We're all familiar with how many bizarre food flavors exist in today's world. I figured the same basic thread could be made for architecture.
The advantage to strange/interesting architecture over food is that it isn't subject to last only as long as the food does; buildings can last for many years, so theoretically you could visit just about any one of the buildings that will be posted in this thread without worrying about them being gone forever.
What strange/interesting buildings have you come across?
