Jantar Mantar, New Delhi
Most people walk right past Jantar Mantar on their way to somewhere else in Connaught Place — which is a shame, because it takes less time to see than a coffee break. Built in 1724 by Maharaja Sawai Jai Singh II, this stone observatory on Sansad Marg was the first of five he built across India, and it’s still standing nearly 300 years later, a few minutes from Delhi’s busiest shopping circle.
Is it worth the detour? If you’re already near CP, yes. Most visits run 45 minutes to an hour — enough time to walk through every instrument and actually understand what it was built to do, rather than just photograph it.
| Quick Answer
Jantar Mantar Delhi is an 18th-century astronomical observatory on Sansad Marg, Connaught Place, built in 1724 by Maharaja Jai Singh II. It’s ASI-protected, open all seven days (generally 9 AM–6 PM), and entry runs about ₹20–25 for Indian nationals and ₹250–300 for foreign visitors. Nearest metro: Patel Chowk or Janpath, both under a kilometre away. |

What It Actually Is
The name comes from two words — yantra (instrument) and mantra (formula) — so Jantar Mantar literally means ‘calculation instrument.’ That’s accurate to what it was: not a decorative monument, but a working research facility. Astronomers used it daily for years, and the readings helped correct earlier astronomical tables used across the region.
It stopped functioning as an active observatory once Delhi grew up around it — taller buildings blocked the clean sightlines to the horizon that instruments like the Samrat Yantra needed. What’s left today is preserved by the ASI as a historical and educational site, not an active one.
Delhi vs Jaipur: How They Differ
| Delhi | Jaipur | |
|---|---|---|
| Built | 1724 (first of the five) | 1728 |
| Protection status | ASI-protected monument | UNESCO World Heritage Site (2010) |
| Size | Smaller, compact site | Larger, more instruments |
| Setting | Central Delhi traffic circle | Dedicated heritage complex |
If you’ve only got time for one, Jaipur’s is the more complete experience — Delhi’s is the one you can fit into a lunch break.
Getting There
Address: Sansad Marg, Connaught Place, New Delhi 110001.
Nearest metro stations are Patel Chowk and Janpath (Yellow Line), roughly 650–850 metres away — about 8–10 minutes on foot. From IGI Airport, figure 40–50 minutes via the Airport Express + Yellow Line, or a direct cab if traffic’s light.
The Instruments Worth Slowing Down For
Thirteen structures are spread across the grounds. You don’t need to read every plaque — three are worth actually stopping at.
Samrat Yantra
The giant angled sundial everyone photographs. It’s large enough to see from the street outside, and in working condition it could read local time to within a couple of minutes just from its shadow.
Jai Prakash Yantra
A pair of bowl-shaped structures set into the ground, marked with coordinate lines. Astronomers tracked shadows across these to map star and planet positions.
Misra Yantra
Literally ‘mixed instrument,’ combining several smaller devices in one structure, including one historically used to mark noon across multiple cities at once.
(Ram Yantra and Digamsa Yantra are also on-site — smaller, less visually dramatic, but part of the same time-and-position-tracking system.)
What a Visit Actually Feels Like
There’s no long queue here, and it’s noticeably quieter than Red Fort or Qutub Minar — this isn’t a monument most people build a whole day around, and that’s part of the appeal. Walk in, spend 30–45 minutes among the structures, walk out. It works well as a midday break between CP shopping and something heavier on the itinerary.
The one thing worth doing differently from most visitors: read the information boards instead of just photographing the shapes. Without them, it’s some interesting stone geometry. With them, it’s a 300-year-old working experiment you can actually follow.
Go early morning or late afternoon if you can — there’s very little shade across the open plaza, and the stone gets genuinely hot to the touch by mid-morning in summer.
Tickets and Timings (2026)
| Category | Online (ASI portal) | At the gate |
|---|---|---|
| Indian nationals / SAARC & BIMSTEC | ₹20 | ₹25 |
| Foreign nationals | ₹250 | ₹300 |
| Children under 15 | Free | Free |
| Video recording | — | Small extra charge (still photography free) |
This lines up with the discount structure the Ministry of Culture confirmed in January 2026 for ASI’s online ticketing — ₹5 off for Indian visitors, ₹50 off for foreign visitors — so it should hold steady barring a fee revision.

Opening hours are listed inconsistently across sources — most say 9 AM–6 PM, a few older listings still show 6 AM. Confirm on the ASI portal or at the gate before you go, especially around holidays. |
Planning the Visit
- Go early (9–11 AM) for soft light and thin crowds, or late (4–6 PM) for cooler weather.
- Book online if you want to skip the gate queue — it also gets you the small discount.
- Carry a photo ID; it’s occasionally checked.
- Combine it with a Connaught Place walk on either side — it’s a short stroll away.
- Pairing it with Red Fort or Qutub Minar the same day? Do this one first — it’s the shortest stop of the three.
Before you go: water and a hat (April–June), closed shoes (uneven ramps in places), a valid photo ID, and confirmed hours for the day you’re going.
Planning Your Delhi Day Around This
| ⚠ Flag for you
I removed the earlier claims of ‘registered tour operator’ and ‘real local guides, not gate-side freelancers’ — I have no way to verify either, so I won’t assert them. Swap this paragraph for your actual operator details — registration, guide credentials, what you specifically offer — so it reads as a real trust signal instead of generic marketing copy. |
If you’d rather have someone handle the routing, timings, and tickets — [your specific offering here] — Jantar Mantar fits easily into a half-day central Delhi route alongside Red Fort, India Gate, and Connaught Place.

Not really, given the low crowd levels — but booking online saves a little and skips the queue.
Bottom Line
This is the easiest ‘yes’ on a Delhi itinerary. It costs less than a metro day pass, takes less time than lunch, and if you’re anywhere near Connaught Place, it’s already on your route. Skip it only if you’re genuinely pressed for time — otherwise, build in the hour and actually read the plaques.
