The place derives its name from the tank that was constructed by Todar Mal, most likely when he was appointed in the office of Chief Diwan in 1582. The structure of the tank is in a dilapidated state, the reservoir is now dry and used as wheat field. Originally the tank had a flight of seven steps around it which had bathing ghats at each corner and in the middle of each side by a bathing ghat. The tank was filled with water through the arched passage on the eastern side which conducted water through some channel. Currently, only the steps on north and a brick platform with arched passage exist.
The mosque is situated to the south of the tank of Todarmal. The main structure is located on the west side of a high platform with cells which might have been the residence of Imam or as a small madrasa. A gateway provides access to the platform from the east side. The mosque is a rectangular building divided into three bays. The facade of the mosque also corresponds with the interior and is delineated into three rectangular recessed archways with the central one higher than the other two. A low dome sitting on a drum spans the interior of the building. The entire facade is divided into sunken panels, which were originally filled with tiles of various colours.
Two graveyards locally known as khanqahs or hospices, indicate that some Muslim saints settled near the bank of the reservoir. Graveyard -1 comprises a square structure built around a courtyard with eight graves located within the courtyard. The walls enclosing the court are decorated by arched niches. The western wall rises higher than the rest of the walls and has a deep recess and a mihrab. Exterior of the structure is also decorated with recessed arched niches. The second graveyard houses, thirteen graves in the courtyard. A tall wall stands on the west of the graves, with a deep recess which serves as a mihrab. Both the structures are Constructed of brick and finished with plaster and paint.
