This is not one of the original seven planned gates of the walled city, it is a later addition. Made during the time of Maharaja Man Singh, it is officially known as the Man Gate but popularly called New Gate. Though the design of this gate is similar to the others, the sidewalls could not be made due to lack of sufficient space.
Come out through the gate and walk straight ahead to the metal gates. After you have crossed an open ground on the left (unless there is an exhibition on) and a parking lot on the right, you will come to a busy traffic intersection.
This is Mirza Ismail Road and beyond the gates is the Ram Niwas Bagh (it includes Ram Niwas Garden, Jaipur Zoo, etc.) and the clearly visible Albert Hall Museum.
