If museums are on your list of things to see, you might want to browse the collections at Agra Marble Emporium in Sadar Bazaar. If you want to experience more of the culture Agra has to offer, head to Sadar Bazar, Agra Fort, and Jama Masjid.
If you're planning a bit of sightseeing head to Agra Fort— just one of the monuments in Rakabganj. Agra has other landmarks you might want to visit such as Taj Mahal.
