Alaudeen Gate, Delhi.

The Alauddin Gate of Delhi is known as Alai Darwaza

[Original caption] Built by Alaudin Khilji in 1310 A.D. [end]

Alai Darwaza is said to be among the first buildings in India to be based on Central Asian and Muslim design principles. Note the restoration cement on the top portions of the building to keep it from falling apart, apparently still there as the building awaits restoration to its early 14th century glory.
