1 Best Sight in Singapore

Part of Marina Bay Sands, this Moshe Safdie–designed structure is often compared to an open hand or a lotus flower. Inside, the exhibitions combine—you guessed it—art and science. Since its opening in 2011, major international exhibitions have been set up within the 21 gallery spaces, totaling 50,000 square feet. Guided tours leave at 4 and 5 pm from the Exhibition Entrance on basement level 2. Upstairs, the Sweet Spot has excellent coffee, cakes, and snacks.
