I just love the clean lines and imposing architecture of this beautiful monument, and its setting in well laid out gardens. There are some really nice other monuments alongside (included in the same ticket), especially the tomb of Isa Khan with its sunken garden.
Use the CaptivaTour audio guide on your phone to get the most out of your visit - its really well written and the stories and details are really interesting. For example, what is a star of david doing on an islamic tomb?
Best visited in the early morning or the late afternoon
