The Shish Gumbad (meaning glass dome') because the dome and parts of the facade were once covered with coloured glazed tiles; it faces the Bada Gumbad. Home to several unidentified graves, it is said to be the tomb of the first Lodi emperor Bahlol, who died in 1489. So the Sheesh Gumbad  is  home to many graves containing  unidentified inhabitants in them.

Historians believe not all belong to the same family of the then rulers and some  argue that they  belong to the Lodi  family and of Sikandar Lodi’s court  or first Lodi emperor Bahlul Lodi (died in July, 1489) and his family.

Above image:  Shish Gumbad: The building shows signs of aging and lack of periodic upkeep. The earliest domed structure is plagued by Missing of finial, colored tiles,  Capital of minaret, plaster and faded dome,  stains in the window opening, growth of vegetation, etc and they need to be rectified as part of renovation .........

There are four monuments ( places of burial or tombs) in the Lodhi Gardens including the Shish Gumbad. The oldest of the four burial relics is the grave of Muhammad Shah (of the Sayyid dynasty).

Believed to have been built between 1489-1517 CE by  Sultan Ibrahim Lodhi,  the Sheesh (or Shisha) Gumbad, (facing Bada Gumbad) in the Lodi gardens, Delhi  was known for its shining glass dome that was once adorned  with coloured glazed tiles , particularly in the central part.  Exact date of construction is debatable so are the names of the people buried there.

The design style of the gumbad, square in plan  with western wall provided with mihrab for prayer (suggesting its use as mosque) and openings on three sidewalls  to reach the inner portion, besides two arched opening (made by Bracket and Beam method) in walls for light aeration   all these attribute to the mark of Lodi architecture. Yet another noticeable feature is though a single story solid building, externally it looks like a two story  structure; this is caused by false doors and windows on the facade.
