Man Mandir Palace and Jantar Mantar – Varanasi

The imposing Man Mandir Palace is one of the major central landmarks along the string of ghats that line the west bank of the great Ganga in Varanasi (Banaras, Kashi). The palace was built in 1585 by the Sawai Man Singh, the Rajput king of Amber (Jaipur in present day Rajasthan) and General of the Mughal Emperor Akbar.

The interior of the Palace has a number of rooms that act as a sort of information centre, although quite a lot of the space is very sparsely used. A few artifacts are on display mostly relating to the Amber dynasty, but my overriding feeling was one of a great opportunity not being fully realised.

Being located so central to the ghats with literally thousands of visitors walking by every day, I felt that a lot more could be done here to provide some detailed historical context to Varanasi. This is after all one of the oldest cities on the planet, so rich in history and stories, and yet none of that was portrayed very successfully at all. To be perfectly honest, my main reason for visiting the Man Singh Palace wasn’t for anything inside the building, the attraction for me was waiting the roof.

The roof of the Man Singh Palace has a surprise in stall or anyone with no prior knowledge of what to expect. Here a set of futuristic looking astronomical instruments of a Hindu observatory was built in 1737 by Sawai Jai Singh II, a descendant of Man Singh.

This is the third such Hindu observatory I have visited in India, the others being in Jaipur and Delhi. The difference here is that the instruments have been distributed in quite a compact fashion across the split roofs of the Man Mahal, as opposed to being more dispersed in open space at ground level.

Despite the obvious limitations for space, most of the instruments in the observatories in Jaipur and Delhi can also be seen here, just not to the same scale. Sadly the urbanisation of Varanasi in the proceeding 300 years since these instruments were built has rendered some of them non-functional in the early mornings and late evenings, as the sunlight is blocked by taller surrounding structures.

Some of the instruments you can see here are as follows :

Samrat Yantra

Sometimes known as the “Supreme Instrument”, the Samrat Yantra is an equinoctial sundial of enormous proportion. It measures time in a similar way to a sundial, but to a precision that had never been achieved before.

The larger the Samrat Yantra, the more accuracy that can be achieved. The two Samrat Yantras here at Varanasi are relatively small, the largest I have seen is in Jaipur which amazingly is capable of measuring time to an accuracy of two seconds.

Dakshino Bhitti Yantra

This is used to measure the altitude of astral bodies. It assisted in the calculation of summer and winter solstices as well as the equinoxes, and thus the progress of the seasons could be tracked.


This is an equatorial sundial used for measuring the local solar time at the latitude of Varanasi.

Chakr Yantra

This instrument measures the declination of the sun, moon and stars, together with their hour angle from the meridian.

Digamsa Yantra

This measures the azimuth, the angle of an astral body relative to a specific observation point. This is the only instrument that is visible from ground level on Man Mandir Ghat, but all you can see is the hint of the curved outer wall.

Whilst you’re up here looking at the instruments, it’s well worth heading over to the eastern edge of the rooftop to catch a glimpse of the ghats down below.

Sawai Jai Singh II

Sawai Jai Singh II was a great admirer of science and technology, and he was particularly passionate about astronomy. In the early 18th century he sent his scholars to several countries to study design, construction, and technology of observatories. The scholars returned with their observations and manuals on astronomy, after which Jai Singh embarked on a campaign of constructing his own observatories between 1724 and 1737 in five locations; Jaipur, Mathura, New Delhi, Ujjain and Varanasi.

By the middle of the 19th century the observatory was in a dilapidated condition. In 1912, Pandit Gokul Chand Bhavan, the then court astronomer to Maharaja Sawai Madho Singh of Jaipur, carried out major restoration work. The observatory today is under the care of the Archaeological Survey of India.

Despite the disappointment of the Man Mandir interior, the Jantar Mantar instruments up on the roof are well worth visiting, especially if you have not recently seen their larger siblings in either Jaipur or Delhi. These structures with their striking combinations of geometric forms still have a futuristic feel to them after 300 years, and offer something a little different in the ancient city of Kashi.

  1. Hi Kevin,
    Great insights into Varanasi. Amazing place, you are doing a wonderful job documenting all this with some great images to boot!
    Really surprised to hear about the Kashi Vishwanath Corridor Project. Great to have temples resurrected from the grave as it were, coming into clear sight after so many years hidden but have any been completely demolished in the process of this new development?

    I was also wondering if you were aware or had already visited this place. Well worth a visit in my opinion.

    The Bharat Mata temple. Which was inaugurated by Mahatma Gandhi in 1936. It is built in marble and houses a model of undivided India, depicting the mountains, plains and oceans.

    Stay safe my friend
    Om Namah Shivaya.
