World Monuments Fund, which says this about the citadel:
The magnificent complex, also known as Sonar Kila (Golden Fort) for its gleaming golden sandstone walls and buildings, flourished on the east–west caravan route connecting India and Central Asia to the Middle East and North Africa. Merchants built elaborately designed Havelis among the numerous palaces, temples, bazaars, and residences inside the walls of the complex. The superb architecture within the fort was protected by double fortification walls and circular bastions, key physical components used for defense and battle. Additional features of the fort include a pitching wall to hold the clay soil of the hill in place, a toe wall, and the Mori, a pathway between the inner and outer fortification walls that allowed soldiers and horses to move throughout the structure in times of war.
