Buland Darwaza

Buland Darwaza (Hindi: बुलंद दरवाज़ा, Urdu: بُلند دروازه‎,pronounced [ˈbʊlənd̪ d̪ərˈʋaːzaː]), or the "Gate of Magnificence", was built in 1601 A.D. by Akbar to commemorate his victory over Gujarat. It is the main entrance to the palace at Fatehpur Sikri, a town which is 43 km from Agra, India.

Buland Darwaza is the highest gateway in the world and is an example of Mughal architecture. It displays Akbar's empire.

The Buland Darwaza is made of red and buff sandstone, decorated by white and black marble and is higher than the courtyard of the mosque. The Buland Darwaza is symmetrical and is topped by large free standing kiosks, which are the chhatris. It also has at the top center, terrace edge gallery-kiosks on the roof, stylized buckler-battlements, small minar-spires, and inlay work with white and black marble. On the outside a long flight of steps sweeps down the hill giving the gateway additional height. It is 40 metres high and 50 metres from the ground. The total height of the structure is about 54 metres from the ground level. It is a 15-storied high gateway acting as the southern entrance of the city of Fatehpur Sikri. The approach to the gate consists of 42 steps. It is semi octagonal in plan and two smaller triple-storeyed wings on either side. It has three kiosks on its top surrounded by thirteen smaller domed kiosks. There are smaller turrets surrounding the gateway. The expanse is broken by arched niches, small chhatries and marble highlights. It highlights the courtyard of the Jama Masjid. The principal arch stands in the centre of three projecting sides and topped by a dome. The central arch is broken into three tiers with rows of smaller arches and flat brackets.
