Aside from Kampong Glam, Chinatown and Little India, Singapore feels largely devoid of any "sense of of history." I don't mean this as a slight(it's a fantastic place), just an observation. There's a "sameness" of it all that can feel almost unsettling at times. Hong Kong is similar in this respect - a place that looms large in history and yet any semblance of the past has largely been erased from the cityscape.
