The Keong Saik road in Singapore has seen itself transformed from a residential area to a red-light area to the current commercial area over the years.
Because of its proximity to Smith Street, which was a well known red-light district at the turn of the century, Keong Saik Road evolved into to a red-light area in the 1960s as many sex clubs and brothels came to be situated in the three-storey shophouses that lined both sides of the street. Since the 1980s, most of the brothels have moved out of the area, though you can still find some prostitution from the Keong Saik Road.
