How did Mughal palaces become as cold as ice without AC? You will be stunned to learn the technology
Mughal Palaces: Nowadays most people use AC to keep their house cool during summer. But, in the olden days there were no ACs, so have you ever wondered how the kings and Maharajas kept their palaces cool? Let us tell you about it.
Lattice windows
Big doors and windows were made in the palaces so that the air could flow easily inside the palace. Also, latticed windows were used. Air came in through the latticed windows but sunlight did not come in. This kept the palace cool.
Water Fountains
Water fountains were also installed in the palaces. The water evaporated, which reduced the surrounding temperature. This helped in reducing the heat inside the palace.
Thick Walls
In the olden days, palaces were designed in such a way that the heat could not reach inside the palaces. For this, the walls of the palaces were made thick. Due to this, the heat could not reach inside the palace. The walls of the palaces were used to absorb the heat.
Trees & plants
Complete care was taken of the greenery inside and around the palaces. Trees and plants were planted around the palaces. Different varieties of trees and plants added to the beauty of the palace and the shade of the trees kept the palace cool and also provided oxygen.
Pond
While building a palace, kings, and emperors also used to build ponds and lakes inside or around it. This kept the atmosphere moist and the heat was less.
