Hanoi - Old Quarters from Higher Up
It is always interesting to observe a city from a higher vantage point. You can see the city pattern, and how it has grown over the years.
From here you can see that the Old Quarters is essential a network of narrow streets. Unlike modern cities which are very regimented, here the city looks organic and "lived-in". People are still building and adding on to the existing structures, kind of like a living-organism which is still growing.
