Amber Fort 

Amber was once, the capital of the Mina tribes, believed to be the original inhabitants of this region. Located up on the hills that surround Jaipur, the fort, sprawled along the Maotha Lake, boasts of a massive complex gateways, courts, stairways and pillared pavilions, and palaces that recall the glory and wealth, of Amber's association with the Mughals. This complex was built by Raja Man Singh, Mirza Raja Jai Singh and Sawai Jai Singh, over a period of about two centuries. 

The front courtyard of the complex, is adorned with the magnificent, pillared hall of the Diwan - i - Am, and the two - tiered painted gateway Ganesh Pol. The palace of mirrors, Sheesh Mahal, is of special interest. It has walls inlaid with exquisite mirrors. The Jas Mandir, perched on the upper floor, is a superb amalgam of Mughal and Rajput style of architecture, as is evident from the exquisitely carved Jali screens, and fine mirror and stucco work.
