"Agar firdaus bar ruh zameen ast, hameen ast o hameen ast o hameen ast!"

The Red Fort, also known as Lal Qila is a historic Mughal fort in Delhi, India, that served as the primary residence of the Mughal emperors. Emperor Shah Jahan commissioned the construction of the Red Fort on 12 May 1639, following his decision to relocate the Mughal capital from Agra to Delhi. Originally adorned in red and white, the fort's design is attributed to Ustad Ahmad Lahori, the architect behind the Taj Mahal. The Red Fort represents the pinnacle of Mughal architecture during Shah Jahan's reign, blending Persian palace influences with indigenous Indian architectural traditions. (Wikipedia)

We entered the Fort through the Lahori Gate which faces Lahore, as told to us by our guide. And, of course, there is a Delhi Gate in Lahore. 

Amir Khusrau's lines, "Agar firdaus bar ruh zameen ast, hameen ast o hameen ast o hameen ast!" (If there be a paradise on earth, this is it, this is it, this is it!), are inscribed on the walls of the Diwan-i-Khas within the Red Fort. 

Lal Qila is massive. (The Red Fort in Delhi covers an area of approximately 255 acres (103 hectares), enclosed by 2.41 kilometers (1.50 miles) of defensive walls. ) The Yamuna River is at the back of the Fort. The Yamuna also flows through the Nizamuddin area. 

We didn't get there until 3 pm but a full tour requires at least a full day. There are so many Mahal, gardens and monuments inside the Fort, not to mention the 5 different museum buildings. We were only able to see the first one and that too only half of it.
