there are a lot of tombs to visit in agra and I was able to see three of the well-known ones.

tomb of akbar the great

tomb of itmad-ud-daulah

tomb of mumtaz mahal

i took these last four pictures at mehtab bagh, which is opposite the taj mahal along the yamuna river and gives the mausoleum a different view.  it used to be a complex with a garden and fountains.  i was told that this site offers a good picture of the taj mahal during night time.
