When you're in Bangkok, visiting the famous Chatuchak weekend market, one of the building nearby is famous and worth a visit.
It's Thai name is Tuk Chang, better known as the elephant building. It's regularly voted one of the ugliest buildings in the world, but the owners prefer to use words like 'notable' or 'iconic'.
If you imagine a 3 legged elephant drawn by a toddler on an etch-a-sketch, then that is pretty much what the elephant building is. But in a way, the terrible design makes it more appealing. The Yang to the Ying of modern life.
