The Tripolia Gates in Delhi are two historical gateways quite similar to each other; they are located on GT Karnal Road, 250 meters apart in the area between Rana Pratap Bagh and Gur Mandi in North Delhi. They were  entrances towards a market from both ends. The northern gate is restored and the southern gate is not yet restored. The two facing gateways have three arched openings  roofed by flat domes. There are  innumerable historical  monuments in Delhi and across India  and many of them are gradually crumbling for reasons of negligence, lack of funds and lack of interest in heritage structures.  Only in the past, both the state and central governments woke up from the long slumber and realized the importance of these vestiges of by-gone era. At many sites, they are subject to degradation  and abuse by anti-social people and drunks, particularly, when they are not properly barricaded or well protected with guards.  The ASI took the initiative and asked the Delhi administration to ban the movement of heavy vehicles through the gateways as this  might damage the structure and make it sink further.

The Tripolia Gateways in Delhi,  the remnants of Mogul era, are land marks in  this sprawling city.  The gate is a set of two facing gateways built for the convenience of administration and control of movement of people in the past. First commissioned in 1728 by

Nasir Mahaldar Khan, an official 
 of women's quarter in the palace of Mughal emperor  of Mughal emperor Muhammad Shah during the period 1728-29,  these  gateways are unique, unlike other gateways that may have one or two passages. Tripolia has  a triple passage. The  Kashmiri Gate has more than one passage. In the past the Mogul rulers used  these gate ways often.

Normally, Tripolia gateways are made up of bricks and sandstone
layers, the two facing gateways have three arched openings and 
flat domes  and lime- plaster finish.  The gates were often  used
 by Moguls  and when they feared an attack, the gateways’ massive doors  were pulled down.   and lime- plaster finish. The walls 
of  the gateways are built 1.5 m into the  raised ground level. 
The purpose is  the connecting passages between the roadways 
that  have waist-high sandstone barriers  could be used to pass underneath them. The gate must have had better plaster coating 
that could withstand  the ravages of time.  In some gate ways  
there   are jharokha (overhanging enclosed balconies) in the main structure openings on either end at the upper level. The  red sand stones   with which they are made of, give an impressive look. 
The restoration is going on in the other gate. It is a belated response. 

In one of the gates, the fine calligraphy in the lower level and the stonework either became too faded or crumpled almost beyond resumption. The calligraphy at  the upper reaches of the arches  and the inscriptions there, etc have survived the time. The other gate needs urgent repair. In the past the gateway sank  a foot or two below ground level  due to heavy motor vehicle traffic. Further, the road level also increased  every time when laying a fresh coat of asphalt.  The roof was damp because of seepage of water during rainy time. This further complicated by moisture problem.

Shah-Quil Khan, apart from being a great warrior he was close to Emperor Akbar. He was a noble in his court and held the post of the Governor of  Punjab. He got the post in 1575 AD and died in Agra in 1601 AD. Narnaul,  being his favorite place Shah Quil had spent much part of his life here. Keenly interested in erecting buildings, he focused his attention on a nice garden in that time  and named it as Aram-i-Kausar.  His yet another contribution is the Tripolia Gateway,   the main entrance to the beautiful  garden. Within the precincts of the garden compound, the gateway is an  elegant three-story structure made with  rubble masonry and  thick layer of lime plaster. The interior walls and ceilings of the fa├žade have beautiful ornamental carvings done with particular care. The inscriptions on the  pointed arch of the entrance gate mention the name of the garden, its builder and the date of its construction.
