Cambodia was once part from French Indochina and they didn't regain independence until 1953. The influence of the French can be predominantly seen the the beautiful but crumbling architecture. It seems today that the buildings are in heightened states of disrepair exacerbated by the forced exodus of the people into the countryside by the Khmer Rouge. Urban areas were left largely unpopulated and many structures began to fall apart. Now so many are in such poor condition and because they're a reminder of colonialism there seems to be little interest in restoring the buildings. It's a shame because they are attractive and functional; their floor plans might not be the best by current standards but the greenest building is the one already built.
