information about entrance gate at Agra fort in uttar pradesh?

Answer 1

There are two main gates in Agra fort
*Amar Singh Gate (or Lahore gate)
*Delhi Gate ( http://www.collectbritain.co.uk/personalisation/object.cfm?uid=019ADDOR0000559U00000000 )

There is also an Old Water Gate

The Delhi Gate is considered the grandest of the gates and leads into an inner gate called the Hathi Pol (Elephant Gate). Due to the fact that the Indian military (the Parachute Brigade in particular) is still using the northern portion of the Agra Fort, the Delhi Gate cannot be used by the public.

Tourists enter via the Lahore Gate. Lahore Gate is named so because it faces Lahore, now in Pakistan. You can find a picture of this gate here:
