I took this snap fearing some fierce hazy lines, but thankfully there were none. Esplanade is the Singapore’s art and culture hub. The curiously glittering blue diamonds are parts of the roof of the Esplanade (The building itself is out of view). It looks like a spacecraft hiding behind the Anderson Bridge. But I guess the only reason it looks so is because the architects drew inspiration from the Durian (the staple fruit of Singapore).
P.S. Read here if you want to know more about the Singapore River.
