Gyarah Sidi Agra: Humayun's Observatory Guide

Hidden away in a quiet village on the far bank of the Yamuna, almost directly opposite the Taj Mahal, lies one of Agra's most intriguing and least-visited relics: Gyarah Sidi, the ruined observatory of the emperor Humayun. This guide from Delhi Agra Tour Packages covers what Gyarah Sidi is, the fascinating story of Humayun and the stars, its location near Mehtab Bagh and how to visit, so you can add this unusual piece of Mughal history to your trip, whether on its own or as part of a Golden Triangle tour.

I was born in Delhi and in more than 11 years guiding travellers across the region for Experience My India. I have always loved sharing Agra's lesser-known corners and Gyarah Sidi, with its eleven carved steps and its tale of an emperor who ruled by the planets, is one of the most memorable. Here is what to know.

Gyarah Sidi at a glance

What is Gyarah Sidi?

Gyarah Sidi, whose name translates as eleven steps, is the ruined remnant of an astronomical observatory built by the Mughal emperor Humayun in the 16th century. What survives today is a freestanding flight of eleven carved red sandstone steps, standing quietly amid the fields and lanes of Kachhpura village on the north bank of the Yamuna, a modest but historically fascinating structure that most visitors to Agra never see.

The steps overlook a set of hemispherical cavities and calculation holes set into the ground, which were used to measure the lengths of shadows and to track the positions of celestial bodies and a circular brick-and-sandstone stepwell or baoli, lies nearby. It is a simple, ruined site rather than a grand monument, but for anyone interested in Mughal history and the story of astronomy in India, it is a genuinely special place, made all the more atmospheric by its quiet rural setting so close to the great Taj Mahal.

The story of Humayun's observatory

The real fascination of Gyarah Sidi lies in its story. The emperor Humayun was deeply absorbed by astronomy and astrology and he used this site to observe the movements of the planets and to schedule major court and military decisions according to what he read in the heavens. For Humayun, the positions of the celestial bodies were not idle curiosity but a guide to the timing of the most important affairs of state.

Historical accounts record just how far this went. Humayun and his ministers are said to have coordinated even their daily attire to match the colours associated with the ruling planet of each day of the week, dressing in particular colours on particular days and assigning different kinds of business, such as government matters or military affairs, to the days governed by the appropriate planet. It is a vivid glimpse into the mind of a Mughal ruler for whom the cosmos and the court were intimately connected and it is this human story, as much as the stones themselves, that makes Gyarah Sidi worth seeking out.

The eleven steps and the design

The structure that gives Gyarah Sidi its name is a freestanding flight of eleven steps, carved from the warm red sandstone so characteristic of Mughal Agra, the same material you see across the river at the Agra Fort and in so many of the city's monuments. The steps would have allowed the observer to climb and sight along fixed lines towards the sky.

The hemispherical cavities and holes set into the ground below the steps were the working part of the observatory, used to measure the shifting shadows cast by the sun and to help track the heavens through the year. Though modest and now ruined, the design marks Gyarah Sidi as an early and diminutive predecessor of the far more monumental observatories that would come later, the great Jantar Mantars built in Jaipur and Delhi, which share the same essential idea of using built structures to read the sky.

Where is Gyarah Sidi and what is nearby?

Gyarah Sidi sits in Kachhpura village on the north or far, bank of the Yamuna in Agra and its location is a large part of its appeal. It lies very close to the beautiful riverside garden of Mehtab Bagh, famous for its sunset view of the Taj Mahal and almost directly across the river from the Taj Mahal itself, so a visit naturally combines with these better-known sights on the same bank.

Also on this side of the river, a little way off, stands the exquisite Itmad-ud-Daulah, the jewel-like tomb often called the Baby Taj, making the north bank a rewarding area to explore beyond the usual trail. Kachhpura itself is a traditional village and the walk through its lanes to reach Gyarah Sidi, sometimes as part of a local heritage walk, is an experience in itself, offering a glimpse of everyday rural life a stone's throw from one of the wonders of the world. You can see the full range of the city's sights in our Agra attractions guide.

How to reach Gyarah Sidi

Gyarah Sidi is reached via Kachhpura village on the north bank of the Yamuna, the same side as Mehtab Bagh, so most visitors come by road, crossing the river from the main city and then walk the short distance through the village lanes to the site.

Because it is off the main tourist trail and set within a village, a little local guidance helps in finding it and it is easiest to visit together with Mehtab Bagh. For getting around the city generally, our Agra Metro guide covers the city's growing network and for reaching Agra from the capital region our Noida to Agra distance guide sets out the route and if you are extending the trip into the Braj region our Agra to Vrindavan distance guide covers that popular onward journey. A private car with a driver is by far the most convenient way to reach an off-the-beaten-path site like this.

Timings and entry fee

Gyarah Sidi is an open, free site, with no ticket required and it is accessible during daylight hours. There are no formal facilities, as it is a simple ruined monument in a village setting rather than a managed attraction.

Since there is no entry fee and the site is small, a visit takes only twenty to thirty minutes and it is best combined with the nearby Mehtab Bagh and the north-bank sights to make the trip across the river worthwhile. Daylight hours are the only time to visit and the softer light of the morning or late afternoon is the most pleasant.

Best time to visit Gyarah Sidi

The best time to visit Gyarah Sidi, as with all of Agra's outdoor sights, is the cool season from about October to March, when the weather is pleasant and comfortable for wandering the village lanes and the open riverside. This is also the ideal season for the Taj Mahal and the rest of the city, so it fits naturally into a wider Agra trip.

The summer, from April to June, is very hot in Agra and makes an open, shadeless site like this uncomfortable, so a visit then is best confined to the early morning. The monsoon, from July to September, brings some relief and a little green to the riverside. Pairing the site with the city's great sights, such as the red-sandstone Mughal city of Fatehpur Sikri a little outside Agra, makes a full and varied day. Within the day, the gentle light around sunrise or late afternoon suits both the ruins and the nearby Taj view across the water and our wider travel guides cover more on planning the season.

Tips for visiting Gyarah Sidi

• Combine your visit with the neighbouring Mehtab Bagh and its Taj sunset view to make the river crossing worthwhile.

• Allow only twenty to thirty minutes for the site itself, as it is small and ruined.

• Visit in the cool season, October to March and in the softer morning or late-afternoon light.

• A little local guidance helps, as the site is off the main trail within Kachhpura village.

• Wear comfortable shoes for the village lanes and the uneven ground around the ruins.

• Take the chance to see the north-bank sights together, including the Baby Taj a little further along.

• Bring water and sun protection, as the open riverside site offers little shade.

What to expect

A visit to Gyarah Sidi is a quiet, offbeat encounter with Mughal history, a world away from the crowds at the Taj yet right across the water from it. You can expect a modest, ruined structure of eleven carved red sandstone steps set among village fields, with the old shadow-measuring cavities in the ground below and a stepwell nearby and above all the remarkable story of an emperor who read the planets and timed his empire by the stars.

As an attraction it is small and unmanaged rather than grand and its reward is atmosphere and history rather than spectacle. For travellers who enjoy going beyond the obvious, it pairs perfectly with Mehtab Bagh and the north-bank Taj view for a memorable half-day that shows a side of Agra most visitors never discover.
