were originally covered with blue tiles. Char Bagh While the main tomb took over eight years to build, it was also placed in centre of a Charbagh, a Persian-style garden with a quadrilateral layout. It was the first of its kind in South Asia on such a scale. The highly geometrical and enclosed Paradise garden is divided into four squares by paved walkways (khiyabans) and two bisecting central water channels, reflecting the four rivers that flow in jannat, the Islamic concept of paradise. Each of the four square is further divided into 8 smaller gardens with pathways, creating 32 miniature gardens in all (with the mausoleum in the centre), a design typical of later Mughal gardens. The central water channels appear to be disappearing beneath the tomb structure and reappearing on the other side in a straight line, suggesting a Quranic verse which talks of rivers flowing beneath the 'Garden of Paradise'. Standing in the center at the place where the main axes intersect, the tomb is similar in form and position to a garden pavilion. But here it marks the place where the body of the deceased ruler rests. "The garden is about sovereignty, and the mausoleum is about dynasty. When the mausoleum is implanted in a garden, as it is at Humayun's tomb, sovereignty and dynasty are combined in a teleological statement that the king is king as he always has been and always will be." The entire tomb and the garden is enclosed within high rubble walls on three sides. The fourth side was meant to be the river Yamuna, which has since shifted course away from the structure. The central walkways terminate at two gates: a main one in the southern wall, and a smaller one in the western wall. It has two double-storey entrances; the West gate is used now, while the South gate, which was used during Mughal era, is now closed. Aligned at the centre on the eastern wall lies a baradari, which is a building or room with twelve doors designed to allow the free draught of air through it. On the northern wall lies a hammam, a bath chamber. Other monuments Tomb and mosque of Isa Khan: Several monuments dot the pathway leading up to the tomb enclosure from the main entrance in the West. Prominent among them is one that pre-dates the main tomb itself, by twenty years. Constructed in
