It is the east facing gate permitting the rising Sun's rays to fall on the gate, which is considered a good omen. The doors of this gate are strengthened with iron spikes and studs to prevent ramming by elephants during an attack. At the entrance to the gate, two red stone statues of elephants with mahouts stand as sentinels. The gate was also the location for announcing the arrival and departure of royalty by musicians playing the trumpet from a gallery in the gate. The other gates are Karan Pol, Daulat Pol, Chand Pol (a double gate) and Fateh Pol; these provided access to various monuments in the fort. The Karan Pol gate is also braced with iron spikes to prevent battering of the gate by elephants. To the right of this gate is Daulat Pol. Forty-one hand imprints are seen on the Daulat Pol gate wall, in red colour, of the wives of the Maharajas of Bikaner, who committed sati (self-immolation) on the funeral pyres of their husbands who died in battle. Between the main gate and the palace, there is a quadrangle, and then another gate called the Tripolia gate (triple gateway) before accessing the royal chambers. Next to this gate is a small temple called the Har Mandir, where the Royal family used to offer worship. In the quadrangle, which houses a large pavilion with a water pool built in Carrara Italian marble. The Karan Mahal, where public audience was held in the Diwan-i-Am by Karan Singh (1631–39) and his successors till the 20th century, can also be seen in the same quadrangle. Karan Mahal (Public Audience Hall) was built by Karan Singh in c.1680 to mark his victory over the Mughal Emperor Aurangzeb. It is considered as one of the most exquisite palaces built with gardens, which displays the aesthetic sensibilities of the royalty of Rajasthan. It has stained glass windows and intricately carved balconies built in stone and wood fluted columns. Later Rajas, Anup Singh, and Surat Singh, also added a lot of glitter to this palace with inlaid polychrome glass, intricate mirror patterns, and red and gold paint. In the coronation chamber, there is a shored up alcove, which was used as a throne. Phool Mahal ("Flower Palace") is the oldest part of the palace and was built by king Raja Rai Singh of Bikaner, who ruled between 1571-1668.
