This is a newly developed area in the city next to Marina Bay Sands. It has greenery and water mixed in with modern art sculptures. There are also a couple museums and outdoor education about Singapore's greenery and some of its agricultural history.
It gives you a break from the city, and give you something complete different. Futuristic nature. And it's a tourist destination worth checking out.
