This is the basement of Kreta Ayer. It is known as Kreta Ayer Wet Market. Why wet market? The floors and surroundings are often routinely sprayed and washed with water—to the extent of flooding it at frequent intervals—which gave it the name "wet market". (For more information on wet market, you can view it from here.
Look at the newly renovated market, it is spacious and very clean. It is so spacious and suitable for those in wheelchairs to move about. Bravo because the population is aging and we need more places to be user friendly to those in wheelchairs.
