RED FORT was NOT built by Mughal rulers namely Shahjahan during his tenure (1628- 1658 AD) in between 1638 to 1648 AD by Employing Ustad Ahmad Lahauri as Chief architect, but instead what they did was only few modifications.

I will prove it.. read the thread below.

A stone tablet inside Red Fort by modern archeologists proclaims that the Fort was built between 1639 to 1648 AD.

But, a painting of Shahjahan's time preserved in the Boldeian Library, Oxford depicts Shahjahan recieving Persian ambassador inside the Fort in 1928.

How can Shahjahan recieve someone in 1928 in Red Fort if it was built in 1939 AD.

The painting was reproduced in the Illustrated Weekly of India, Page 27, March 14, 1971.
This documentatory evidence disapproves the notion that he build the Red Fort.

In Red Fort’s Khas Mahal, one can find the royal emblem (PIC 3) of its builder King Anangpal. It has of a pair of swords laid hilt to hilt curving upwards, the sacred Hindu pot (kalash) above the hilts, a lotus bud and a pair of scales of justice balanced over it.

Dotted around are representations of the sun from whom Indian ruling dynasties claimed descent (Surya Vansh).
At the sword points are two small conches considered sacred in Hindu tradition. Bigger conches may be seen at the left and right corners at the base.
