This gate is the best example of masonry in use in the time of Sher Shah. It derives its name from a Saint names Sohail Bukhari buried in the south-western bastion of the gate.

It is a double gate rectangular in shape. It is 21.34 meters (70 feet) high, 20.73 meters (68 feet) wide and 15 meters (50 feet) deep. The central archway is 4.72 meters (15 feet) wide. It has an inner and an outer arch which is decorated with beautiful and simple motifs of sunflower. This decoration is repeated in all parts of the fort.

There are balconies on either side of the central arch. These balconies have a small dome and their sides and bottom are also decorated. Unlike other parts of the fort which has been built in Afghan-Persian style, the balcony is an example of Hindu architecture. These same balconies can be seen in Haveli Man Singh. There is a small window in the middle of the outer arch. This window is different from the two balconies to either side of the outer arch. It is much simpler that these two balconies.

There are seven merlons on this gate. The bastions are with battlements which have loopholes. These bastions have three levels on the inside. These can be seen if one zooms in the Sohail Gate picture.The inner side of the gate mirrors the outside but has less decoration. There are no battlements towards the inside and no balconies either. The rooms in the upper storey of this gate have windows that open towards the inside of the Qila. Like the outer arch there is a small window in the middle of the inner arch. The gate now houses a Visitors information center and a Museum.
