The beauty of Humayun’s Tomb and Isa Khan’s Tomb lies in symmetry. While Isa Khan’s tomb is an enclosed octagonal garden, Humayun’s Tomb is like a palace by itself. Vast, and beautifully landscaped, this is one of the must-see places in Delhi. The 30-acre garden is called Char Bagh Garden.  Four central water courses define Char Bagh Garden’s quadrilateral layout. One can easily spend half a day just soaking in the detail in the architecture. And I should mention that the tourism department has done a really good job in maintaining the gardens. I was impressed!
