The city is full of alleys and narrow winding lanes as a network. Built by red bricks as ground and buildings and being full of venders, they are colorful to watch. Each small lane can lead you to some surprises, a temple, a school, a small square, a market... you never know.
Looking up to admire the wood carvings on the temples, I found it's full of erotic theme, on four sides of the temple, all different.
You can find it in Durbar Square, as well as on street temples.
