Sheikh Chilli's Tomb is complex of structures located in Thanesar, in the Kurukshetra district of Haryana, India.

The Qibla in the centre of the western wall is flanked on either side by two arched niches inscribed with verses from the Quran.

The masjid is assignable to the seventeenth Century A.D. Adjoining the southern flank of the complex (i.e. north of the tomb of Sheikh Chilli) is a large sized building which on account of both stratigraphic evidence and style of construction appears to be a garden complex following the pattern of a typical Mughal Garden and is divided into four equal, symmetrical parts (the charbagh pattern) with a square hauz in the centre.

On the eastern side of the central hauz there is a small rectangular tank connected with a raised open drain coming from further east.

The tank had on the northern side a small cistern having cussed patterns on both longitudinal ends and a copper fountain in the center.

The Park now popular as the Harshvardhan Park is entered through an elaborate double storey gateway, located in the center of the eastern wall from which one of the paths leads to all its four sides, hosting on the exterior, a series of double roomed chambers, on three sides i.e., the east, north and west respectively with provision of niches and alcoves on its walls.

The western wing of this sarai however had double storeyed chambers which could be reached through a flight of steps provided at the center and towards the extreme south-western corner.
