The Gallery Hotel 1 Nanson Road 238909 Singapore 4-Star Hotel,223 Rooms The Gallery Hotel is the first and only beyond the ordinary hotel in a usually rather boring and dull Singapore hotel scene. The unconventional, exciting architectural design of the building at Robertson Quay has created much interest from passers-by. As an example, the swimming pool sticks out of the building and has three sides of glass walls. Window frames on some parts of the hotel are in vivid colours and at night the innovative lighting accentuates the structure.
