When you gaze upon this beautiful neo-classic landmark of Singapore, you'd never guess that it used to be a jail and torture chamber! It looks as if it's straight out of a fairyland with its eye-popping rainbow-coloured windows. It's considered one of the finest buildings and one of the best tourist attractions in Singapore. The six-storey building encompasses the Italianate style of architecture with its central courtyards, intricate corbels, arcades, and balconies. However, its exterior is the most-photographed from across the road, where people stand in the middle of the traffic to capture the complete façade with its multi-hued shutters.
