Blue City

The world is full of cities with strange nicknames and one of them is the Blue City of India that is also known as Jodhpur. It got that name because every little building and house in this fortress city is painted in a blue color, so from above it looks like a blue spot in the middle of the Thar desert. It is still unknown why they all painted in the color blue but some will say that it has something to do with the caste system in India.
