Chini ka Rauza is also called as the China Tomb of Agra. This mausoleum belong to a Persian born poet, who rose to the position of Wazir (Prime Minister) during the reign of Shah Jahan. Mullah died in 1639 in Lahore. His remains were brought back to Agra, to be buried in this spot. Just like every other mausoleum of Mughals, the tomb is built to face the holy city of Mecca.
This Mughal structure has many exotic and unusual styles of architecture. The main dissimilarity is the un-proportional dome built in Sultanate style. However, the beauty of the tomb has heavily disintegrated with passage of time. The walls of the monument have worn out, but you can still see the striking enamel colors on the tiles and remains of what used to be a grand ceiling painting. The builders of the tomb used earthen pots to reduce the weight of concrete filling in the facades. This method is widely used in Egypt and Rome. https://www.travelogyindia.com/agra/chinni-ka-roja.html
Fatehpur Sikri was the imperial city of the Mughal dynasty between 1571 and 1584. Built by the Mughal emperor Akbar, this royal city is one of a kind. The architectural grandeur of this deserted city cannot be described in words and one can only experience the aura of its magnificent edifices by seeing them. https://www.tourism-of-india.com/agra/things-to-do/fatehpur-sikri-agra.html
