Malacca (Melaka) has a beautiful historic district; it is even designated a world heritage city (by the United Nations – UNESCO). The atmosphere encourages artistic thought and expression. And that is shown in art as you walk around the city.
Some of the art is maybe not what we normally think of as art. But the painting of walls and shutters gives very artistic views as do arched walkways and other elements of the urban architecture.
And some of the art you can see from the streets isn’t normally called “street art” but the temples provide great artistic views as you walk the streets.
