The tank is considered sacred by the Hindus and is visited by people who on solar and lunar eclipse to take a dip in the holy water. This place was also mentioned by Akbar during one of his visits as best in the suburbs of Delhi. It was re-discovered in 1872 by the British who developed the surrounding tank after realizing its medicinal value. The main structure over the spring is octagonal shaped and covered with a dome, topped with an inverted lotus and a finial. Water from here is delivered into a large cistern. A number of concrete pools receive water from the spring. Today, the domed structure and the tanks have been altered and several other buildings have sprung up around it

The Jahaz Kothi, house in the form of a ship, stands to the east of the Hisar town. It was a large building standing on a platform which was probably surrounded by water. During its lifetime the building performed various functions as an office, a residence, a mosque, and a madrasa. The building above the platform has a central arcaded hall on the western side with pointed arches and cross vaults. The central chamber has a dome it appears to be reconstructed or heavily restored at a later date due to the presence of cement covering. The entrance chamber which is on the eastern side of the platform is out of use and a flight of steps gives access to the platform from the southern side. The building has now been converted into a Jain temple.

Shah Quli Khan built this water pavilion garden after fifteen years from the construction of his mausoleum. This ambitious project is located in close proximity to the tomb complex of Bagh Arami-i-Kausar. Greater importance and architectural finesses is given to the pavilion now called the Jal Mahal, which was set in the middle of a large water tank with a garden enveloping the entire ensemble. The entrance to the pavilion is from north through a Gate House with rooms for the guards, constructed over a bridge rested on sixteen arched spans. The architecture of the pavilion reflects the emergence of “Hindu-Muslim-Akbaride” style. The decorative interiors of the pavilions are beautiful especially the painted ceiling which seems to have been adopted from some Rajput Palace, most probably of Amber near Jaipur. A temple building with a water tank attached to it was added at the north-east corner of the Jal Mahal Tank, during the 18th century AD. The Jal Mahal complex is a protected monument of ASI.

Accessible through a number of steps, this temple is located within an open court. Building plan is linear with a large hall with three bays, separated by arched openings.

Interior of the domes are decorated with paintings while the exterior is ribbed, plastered and topped with finials. Two minarets are located at the front corners building. The interior of the structure that was originally a Jami mosque, has undergone several alterations due to its new use as a Durga temple.

The Jama Masjid is situated in the middle of the town. The mosque was erected in AD 1531 in Humayun?s time as inferred from the inscription under the pulpit stairs. Outside, over the south arch is another inscription of the time of Aurnagzeb, AD 1667-1668, stating that the mosque was built by Khwaja Rahmat Ullah by order of the Emperor in the tenth year of his reign. But there are two Arabic inscriptions which tend to show that a mosque existed here even before the reign of Humayun. Currently the mosque is in reuse as a Gurudvara but the structure has remained unaltered despite its current religious status.
