When you step onto Naqsh-e Jahan Square in Isfahan and turn your gaze upward, the first thing that strikes you is not the size of the square or the rhythm of its arcades. It is the domes. Two domes, each a different shade of blue, catch the light and hold it, throwing colour across the paving stones below. One is the great turquoise dome of the Shah Mosque, rising behind its entrance portal at the southern end of the square. The other is the pale, almost cream-coloured dome of the Sheikh Lotfollah Mosque on the eastern side, its surface patterned with such density that from a distance it looks like a piece of woven fabric draped over a hemisphere. These are the jeweled domes of Isfahan, and they represent the high point of Islamic tilework in Iran.
The word "jeweled" is not mere decoration. In Persian, the term kashi-ye haft-rangi refers to the seven-colour tile technique that reached its peak in Isfahan during the Safavid period. Each tile is painted with up to seven distinct pigments, fired in a kiln, and then set into the surface of the dome in geometric and floral patterns that interlock with mathematical precision. The result is a surface that shifts in colour and intensity depending on the angle of the sun, so that the dome appears different at dawn, at noon, and at sunset. This guide walks through the two great domes on Naqsh-e Jahan Square, explains the techniques behind them, and shows you how to visit them as part of a day in Isfahan.
Where are the jeweled domes of Isfahan?
The two principal domes are located on Naqsh-e Jahan Square, the UNESCO-listed public square in the centre of Isfahan. The Shah Mosque (also known as Imam Mosque) occupies the entire southern side of the square, and its dome is visible from every point on the paving stones. The Sheikh Lotfollah Mosque stands on the eastern side, directly opposite the Ali Qapu Palace, and its smaller, more delicate dome is a study in subtlety compared to the grandeur of its neighbour.
A third dome worth mentioning is the dome of the Jameh Mosque of Isfahan, located about a ten-minute walk north of the square through the bazaar. The Jameh Mosque is older than the Safavid period, with origins going back to the ninth century, but its dome chambers, particularly the south dome built under the Seljuks in the eleventh century, are masterpieces of brick geometry that prefigure the later tiled domes of the Safavid era.
All three domes are within walking distance of each other in central Isfahan, and a single visit to the city can comfortably encompass all of them. Isfahan sits in central Iran, on the banks of the Zayandeh Rud, roughly 340 kilometres south of Tehran by road.
How to get to Isfahan and to Naqsh-e Jahan Square
Most visitors arrive in Isfahan from Tehran. The distance is about 340 kilometres, covered in roughly four to five hours by car. Here are the main transport options.
By Mehyar Taxi. The most flexible way to reach Isfahan from Tehran, or to move between the city's monuments, is to open Mehyar, choose Taxi, and set your destination. A private car gives you the freedom to stop at viewpoints along the road, to rest when you need it, and to arrive at Naqsh-e Jahan Square ready to walk rather than tired from a bus journey. Within Isfahan, Mehyar Taxi is the quickest way to get from your hotel to the square and back.
By Mehyar Buses. For budget travellers, Mehyar Buses connects Tehran to Isfahan with comfortable coaches that run frequently throughout the day. The journey takes about five to six hours. From the Isfahan bus station, a short taxi ride brings you to Naqsh-e Jahan Square.
By plane. Isfahan has an international airport, Shahid Beheshti Airport, with domestic flights from Tehran and several other Iranian cities, as well as limited international connections. From the airport, it is about a thirty-minute taxi ride to the city centre.
By train. Isfahan does not yet have a passenger railway station, though one is under construction. For now, the nearest rail access is at Shahin Shahr, about forty kilometres north of the city.
What to see: the domes and their tilework
Each of the great domes on Naqsh-e Jahan Square tells a different story about Safavid art and architecture.
The dome of the Shah Mosque (Imam Mosque)
The Shah Mosque was commissioned by Shah Abbas I in 1611 and took roughly twenty-six years to complete. Its double-shelled dome rises to a height of about thirty-two metres from the floor of the prayer hall to the apex of the outer shell. The outer surface is covered entirely in haft-rangi tiles, arranged in spiralling floral patterns that radiate from a central medallion. The dominant colour is turquoise, but close inspection reveals layers of cobalt blue, white, yellow, and green, all working together to create a surface that seems to vibrate with light.
The double-shell construction is significant. The outer shell is slightly taller than the inner one, and the gap between them creates an insulating air layer that helps regulate the temperature inside the prayer hall. The inner shell, visible from within the mosque, is decorated with painted plaster rather than tiles, and its geometric pattern of interlocking stars and hexagons is equally impressive.
To see the dome from the best angle, stand in the centre of the square and look south through the entrance portal. The dome appears framed by the iwan, its turquoise surface glowing against the sky. Then walk into the mosque, pass through the entrance corridor that turns forty-five degrees to align the prayer hall with Mecca, and stand in the courtyard looking up. From here, the full complexity of the tilework reveals itself.
The dome of the Sheikh Lotfollah Mosque
If the Shah Mosque dome is a declaration, the Sheikh Lotfollah dome is a whisper. Built between 1603 and 1619 for the court mosque of Sheikh Lotfollah, the scholar and father-in-law of Shah Abbas I, this dome is smaller and more intimate, but no less remarkable in its craftsmanship.
The dome is single-shelled and rises about thirty-one metres from the ground. Its surface is covered in a dense, cream-and-buff tile pattern that looks, from a distance, like the weave of a fine carpet. The pattern is not symmetrical in the way of the Shah Mosque dome. Instead, it features a spiralling arabesque of peacock tails and floral scrolls that draws the eye upward in a continuous spiral from the base of the dome to the finial at the top.
The colour changes throughout the day. In the morning light, the dome appears cream or pale gold. As the sun moves overhead, it shifts to a soft pink. By late afternoon, it takes on a warm, almost honeyed tone. This deliberate colour-shifting is a signature of the Isfahani tilemakers, who understood that a dome is not a static surface but a canvas that interacts with the sun.
Inside, the prayer hall is one of the most beautiful spaces in all of Iranian architecture. The mihrab is flanked by delicate marble screens, and the dome above is decorated with painted plaster arabesques in gold, cream, and deep blue, so fine that they look like manuscript illumination blown up to architectural scale.
The Seljuk domes of the Jameh Mosque
For a contrast with the Safavid tiled domes, walk ten minutes north through the bazaar to the Jameh Mosque. Here, two brick domes from the Seljuk period (eleventh and twelfth centuries) stand in the southern courtyard. They are not tiled, or rather, the tiles that were later added have largely fallen away, leaving the bare brick structure exposed.
What these domes lack in colour they make up for in structural daring. The south dome, built around 1088, was for centuries the largest single-shell brick dome in the Islamic world. Its proportions, its use of concentric brick rings to distribute weight, and its mathematical precision all set the standard that the Safavid builders would follow five hundred years later when they added the tile skins. Standing in front of these domes, you can see the bones of the art: the geometry that the Safavid tilemakers were decorating.

The art of haft-rangi tilework
The word haft-rangi means "seven colours," and it refers to a tile-painting technique that became the standard in Isfahan during the seventeenth century. Before haft-rangi, the dominant technique was moarraq, in which each colour was cut from a separate piece of tile and assembled like a mosaic. Moarraq produced stunning results but was slow and expensive. Haft-rangi allowed the painter to apply multiple colours to a single tile before firing, speeding up production without sacrificing quality.
The seven colours typically included white, cobalt blue, turquoise, yellow, green, black, and a warm red or orange. The painter would lay out the design on the unfired tile using a fine brush, then the tile would be fired in a kiln to set the glazes. After firing, the tiles were set into the surface of the dome or wall in a predetermined pattern, with the mortar lines carefully aligned so that the overall design was continuous.
On the domes of Isfahan, the haft-rangi technique reaches its highest expression. The curvature of the dome means that each tile is slightly wedge-shaped, and the painter must account for this distortion in the design. The result is a surface that appears to flow like water, with patterns that seem to shift as you move around the base of the dome.
Best time to visit the jeweled domes
Isfahan has a semi-arid climate with hot summers and cool winters. The best time to visit the domes is in spring or autumn, when the light is warm and the skies are generally clear.
Spring (March to May) brings mild temperatures and occasional rain. The light is soft and diffused, which is ideal for photographing the domes, as the colours appear at their most subtle and layered.
Autumn (late September to November) offers clear skies, comfortable temperatures, and long golden light that makes the turquoise of the Shah Mosque dome glow. This is probably the single best season for appreciating the colour effects on the domes.
Summer (June to August) is hot, with temperatures regularly above thirty-five degrees. The midday sun bleaches the colours and makes the square uncomfortable. If you visit in summer, go early in the morning or late in the afternoon.
Winter (December to February) can bring cold, grey days that mute the colours. But a winter sunrise, when the first light hits the Sheikh Lotfollah dome and turns it from grey to gold, is an experience worth the early alarm.
For the best light on the domes, arrive at Naqsh-e Jahan Square about an hour before sunset. The low sun throws the tile patterns into sharp relief, and the turquoise of the Shah Mosque dome takes on a depth of colour that is impossible to see at midday.
