Jantar Mantar — Attraction in New Delhi

Overview Jantar Mantar in New Delhi is an astronomical observatory built in the 18th century. It is a testament to the scientific and architectural ingenuity of the past, consisting of a collection of colossal masonry instruments used for astronomical observations. It's one of five such observatories built by Maharaja Sawai Jai Singh II of Jaipur, who was a passionate astronomer and a patron of science. While it may not serve its original scientific purpose today due to the surrounding tall buildings, it remains a fascinating historical and architectural site. Historical Significance The Delhi Jantar Mantar was the first of five observatories constructed by Maharaja Jai Singh II between 1724 and 1730, with the others located in Jaipur, Ujjain, Varanasi, and Mathura. He was commissioned by Mughal emperor Muhammad Shah to revise the astronomical tables of the time and improve the accuracy of the calendar. Jai Singh II believed that the smaller, brass instruments used by astronomers were not precise enough, so he built these large, fixed masonry instruments to achieve greater accuracy. The name "Jantar Mantar" is derived from Sanskrit, with "Yantra" meaning instrument and "Mantra" meaning formula or calculation, effectively translating to "instruments for measuring the harmony of the heavens." Architecture and Instruments The architecture of Jantar Mantar is striking, with its geometric, sculpture-like instruments that are both functional and visually impressive. The complex is an open-air observatory with several key instruments, each designed for a specific astronomical purpose. Samrat Yantra: This is the most prominent instrument, a massive triangular sundial (the "Supreme Instrument"). It was used to measure time with remarkable accuracy, with a large gnomon (the arm of the sundial) and a curved scale on which the shadow would fall. Mishra Yantra: This "mixed instrument" is a combination of five instruments and was used to determine the shortest and longest days of the year. It could also be used to find out the precise time of noon in different cities around the world. Ram Yantra: Two large cylindrical structures with open tops, designed for measuring the altitude and azimuth of celestial bodies. Jai Prakash Yantra: A pair of concave hemispherical sundials used to align the position of stars to markings on the instrument's surface. Visitor Experience and Review Jantar Mantar offers a unique experience for visitors, blending science, history, and art. Atmosphere: The site is a tranquil green space in the middle of a bustling city, offering a peaceful environment for exploration. The instruments themselves have a sculptural quality that is very appealing. Educational Value: For those interested in astronomy and ancient science, the complex is an educational marvel. It provides a tangible glimpse into the scientific knowledge and dedication of 18th-century Indian astronomers. Guides (sometimes available) or informational plaques can help explain the function of each instrument. Photography: The striking shapes and colors of the instruments against the backdrop of the sky make Jantar Mantar a popular spot for photographers. Accessibility: Jantar Mantar is located on Sansad Marg near Connaught Place, making it easily accessible by Delhi Metro (the nearest station is Patel Chowk or Rajiv Chowk). Entry fees are low for Indian citizens and a bit higher for foreigners. In summary, Jantar Mantar is a compelling destination for anyone with an interest in history, science, and unique architecture. While its functionality has been compromised by modern buildings, its historical significance and the sheer brilliance of its design make it a worthwhile visit for a glimpse into India's rich...

The name Jantar Mantar is derived from the Sanskrit word Yantra- Mantra which means instruments and formulae / calculations or magical words.

But due to mispronunciation it changed to the known name Jantar Mantar. This ancient astronomical masterpiece is one of the five observatories built under the guidance of Maharaja Sawai Jai Singh II, ruler of Amber, Rajasthan between 1724 and 1734.

He attached himself to no particular school but studied Hindu, Muslim and European method impartially. He collected astronomical books and had translated a few of them. The title "Sawai" was given to him by Mughal Emperor Aurangzeb as a token of respect which meant one and a quarter times superior to his contemporaries. He founded a new city Jaipur near Amber which later became his capital. Jai Singh is accredited as the first Hindu astronomer to have thought of the necessity and importance of erecting the astronomical observatories. He realized these instruments will help the astronomers in observing the movement of Sun, Moon and other planets through which exact predictions could be made. Keeping these objectives in view Maharaja Jai Singh II started the construction of observatories in various cities. The first observatory was built in Delhi followed by other observatories in Jaipur, Ujjain, Varanasi and Mathura in which the last one disappeared long time ago. Large masonry instruments such as those in the Jantar Mantars are unusual anywhere in the world. The Jantar Mantars represent one of the last links with the old schools of astronomy and are an important part of the Cultural and Scientific Heritage of the World. The Delhi observatory consists of several geometrical devices which are fixed structures and point to a specific direction.

At present the general plan of the observatory represents the following major structures: The Samrat Yantra or Supreme Instrument, a huge equinoctial dial. The Jaiprakash Yantra, consisting two hemispherıcal structures. The Ram Yantra, consisting of two circular structures. The...
