As one takes the road to
Hauz-Khas, from its
junction with the Delhi-Mehrauli road, one notices on the north two tombs
on an elevated ground, one larger and the other smaller. The tombs, built
of rubble and plastered, follow the square pattern of Lodi tombs, with
openings on the east, north and south and with the facades broken into
semblance of storeys. 
It is not known who lie buried in them. But the larger one is known as
the tomb of 'Biwi' (mistress) or Dadi (grandmother), and the smaller one
that of 'Bandi' (maidservant), or 'Poti' (granddaughter).
A medival Sanskrit inscription, much obliterated, was recovered here some
years back and the site may represent the location of some Hindu
establishment.
There are several other tombs of different sizes within the Green Park
and its neighbourhood, with popular names like 'Biran-ka-Gumbad'
(brother's dome), 'Chhoti Gumti' (small dome), 'Sakri Gumti' (narrow dome)
etc., but there is no indication of the persons lying buried in them.
