Built between 1588-93 by Raja Rai Singh, a general in the army of Mughal Emperor Akbar, this impressive fort is a formidable structure encircled by a moat. The Suraj Pol or Sun Gate, is the main entrance to the fort. Within the fort are thirty-seven palaces, pavilions and temples, which make a picturesque ensemble of courtyards, balconies, kiosks and windows.
The palaces exquisitely built in red sandstone and marble are ornate with mirror work, carvings and paintings. Among the notable palaces are the Phool Mahal (Flower Palace), which is decorated with paintings and carved marble panels, the Hawa Mahal, Badal Mahal and Anup Mahal. A major feature of the complex is the magnificent stone carving.
The fort also has a fine collection of Rajput weapons and an old World War I biplane presented to Maharaja Ganga Singh by the British. This is one of the only two models of this plane in the world.
