This garden is spread over 90 acres in the heart of Delhi, and contains the tombs of various rulers of the Pashtun Dynasty which ruled much of Northern India during the 16th century. There are lush lawns and a plethora of flowers and plants mixed in with all the monuments. The tomb of Mohammed Shah, the last of the Sayyid dynasty rulers, the earliest of the tombs in the garden, was built in 1444 by Ala-ud-din Alam Shah as a tribute to Mohammed Shah. As there is little architecture from these two periods remaining in India, Lodi Gardens is an important place of preservation. Another tomb within the gardens is that of Sikander Lodi, which is similar to Mohammed Shah's tomb. In the middle of the gardens is the Bara Gumbad ("big dome"); it is not a tomb, but a gateway to an attached a three domed masjid (mosque), both built in 1494 during the reign of Sikander Lodi. Opposite the Bara Gumbad is the Sheesh Gumbad ("glass dome"), named for the glazed tiles used in its construction.
