Hagia Sophia is one of the greatest early Christian monuments in the world.
While planning my trip to Istanbul, I made a list of places and landmarks that I particularly wanted to see. At the very top of the list was Hagia Sophia, a Byzantine temple, one of the largest and most valuable monuments from the early Christian period.
In the article below, I will tell you about my visit to this extraordinary temple, as well as offer advice on the best time to plan your visit and how to prepare for it. Of course, I will provide plenty of information and interesting facts, along with a brief overview of its history.
Hagia Sophia, Istanbul: Tourist Pass a city card that will save you money and time

I’ll start a bit unconventionally, with some advice on how to plan your visit to Hagia Sophia. First, you need to be aware that for the past few months, this monument is no longer a free attraction in Istanbul. The ticket costs quite a bit, around several dozen euros, and this is just for entry to the temple. All other attractions around it, such as the Basilica Cistern or the nearby Topkapi Palace, require separate tickets, which are also not cheap.
Istanbul has become significantly pricier recently, especially noticeable in the prices of tickets for city attractions. There are, of course, a few ways to save a bit; I suggest checking the website, where there are often good sales and interesting deals for purchasing tickets or entire tours.
If you plan to explore Istanbul for many days, a suitable option is to buy the Istanbul TouristPass. It allows you to visit over a hundred attractions across the city, and importantly, you can skip the line at most of them. This is crucial, as you’ll understand when you see the crowds of tourists waiting at the ticket booths. The card not only lets you visit the most fascinating places in Istanbul, but also take part in concerts, Bosphorus cruises, and shorter or longer trips outside the city. We used it ourselves, so I can wholeheartedly recommend it to everyone.
Since 1934, Hagia Sophia served as a museum, but in 2020 it was converted back into a mosque. Therefore, remember that during your visit, the same rules apply as in any other Muslim place of worship. Women need to cover their hair, legs, and shoulders, and men should avoid wearing shorts. Although, as is often the case in the Muslim world, men have a bit more leeway.
Once inside the temple, there is no time limit, so you can freely wander through the corridors and balconies for as long as you wish. This gives you the opportunity to find the famous mosaics scattered throughout the building. Moreover, keep in mind that while it’s allowed to photograph the interiors, you shouldn’t use a flash, especially when taking pictures of the lower part of Hagia Sophia, where worshippers are praying.
Hagia Sophia in Istanbul sightseeing

As I mentioned at the beginning, visiting Hagia Sophia was one of the reasons I travelled to Istanbul. I had long wanted to stroll through this extraordinary temple and see its interior with my own eyes, and there is a lot to see. The dark, aged walls of the church, although filled with Muslim symbols, have retained a clear Christian character.
Hagia Sophia was built in a rather unusual way. The plans of the temple show that it has an almost square base, but once inside, you get the impression that the interior is rectangular. This effect is due to the semi-domes placed on both sides of the main dome, which measures 32 meters. This roof structure visually elongates the vast interior.
To this day, Hagia Sophia remains unique in terms of architecture, as Byzantine builders never again imitated the solutions used in it. The entire temple is essentially a massive basilica space with three side aisles separated by columns, which support the galleries. The gigantic dome is supported by two colossal marble pillars. Pay attention to the marble from which these pillars were made. It is of the finest quality, with a beautiful colour, and was brought from the farthest reaches of Byzantium.
Above the galleries, there are windows in the walls that, on sunny days, illuminate the church’s interior in a very specific way. It appears that the galleries hanging above the temple’s floor are floating in the air, as if levitating. I’m not sure if this effect was intentional or if it can be observed at all times of the day.
Unfortunately, most of the original decorations and ornaments have been lost. Only the marble columns and small fragments of decorations high up on the ceiling have survived. The building has been renovated many times over the centuries, with new decorations often added, sometimes destroying the previous ones. However, what has survived to this day allows Hagia Sophia to be included among the most magnificent and intriguing structures in the world.
Did the visit to Hagia Sophia meet my expectations and was it as impactful as I had hoped? Well, yes and no. The age of the building and its sheer size are truly overwhelming. Walking through the somewhat dim interior, lit by rays of sunlight streaming through stained-glass windows, I could literally feel the majesty of the old church. However, the effect is marred by awkwardly added Muslim elements and the deliberate covering up of the building’s original Christian features. Moreover, the fact that visitors are not allowed to go down to the first level of the temple significantly limits the experience, but, well, you have to take what you can get.
Hagia Sophia and the famous mosaics on the walls of the temple

In the Byzantine Empire, there was a centuries-long dispute over whether it was permissible to venerate figures depicted in images or icons. Some were strongly opposed to creating portraits, believing it was idolatry and contrary to one of the Ten Commandments. Others argued that icons and the saints depicted on them were symbols of their faith. Therefore, most of the mosaics in Hagia Sophia were created after the period of iconoclasm, which eased in the 9th century.
Unfortunately, the mosaics that have survived in the temple to this day are only a small portion of the original decorations. However, if you are attentive and give yourself enough time, you can still find the images that have endured through the challenging centuries for the building. The most famous mosaics include those placed at the Imperial Gate, above the entrance to the temple in its southwestern part, and the depiction of Emperor Alexander located on the church’s ceiling.
The mosaics in Hagia Sophia depicted saints, church fathers, prophets, and angels. Images of Christ and the Virgin with the child often appeared as well. However, old documents reveal that not all images in the temple had a religious character. Among the figures, there were also portraits of emperors and members of the imperial family, suggesting that there was virtually no separation between church and state in the Byzantine Empire.
Today, many of the mosaics have been covered by Muslim elements so that they are not visible to the worshippers praying below. Therefore, you might have to wait in long lines to get to the spots where you can see them.
Hagia Sophia and its history

Hagia Sophia is not the first temple to have stood in this part of Istanbul (formerly Constantinople). In the early third century, Emperor Constantine I, the first Roman emperor to adopt Christianity, ordered the construction of the first church. It was built on the foundations of an earlier pagan temple. Although no details about it have survived, legends say it was dedicated to a terrifying deity that frightened the early Christians, and to completely erase its memory, a church was erected in its place.
The new structure was destroyed by fire, as was the next one, which was demolished during a popular uprising in 532. The revolt broke out due to the emperor’s failure to address rampant abuses in Constantinople and the constant increase in taxes. Despite the emperor’s Christian faith, the uprising was suppressed using old, tried-and-true Roman methods, resulting in the massacre of over thirty thousand discontented citizens.
The destruction of the city gave the emperor an excuse to build a new temple, which would become Hagia Sophia. The church was constructed at an almost express pace, in just six years. The architects of this grand project were two famous scholars, Anthemius of Tralles and the mathematician Isidore of Miletus.
The building you can see in Istanbul today dates back to the 6th century, but over the many centuries that have passed, it has been repeatedly renovated and reinforced. It also faced numerous tragedies, such as the earthquake in 558 that caused the collapse of the main dome. In 1204, Hagia Sophia, along with the rest of Constantinople, was plundered by Venetians and Crusaders during the Fourth Crusade.
The darkest days for the old church came with the capture of Constantinople by the Turks in 1453. Almost immediately, the church was converted into a mosque, and typical Muslim elements, such as minarets and a mihrab (a niche indicating the direction of Mecca), began to be added. The original wooden minarets eventually decayed, and new, stone ones were erected in their place, which still surround the building today.
In 1985, Hagia Sophia was listed as a UNESCO World Heritage Site as part of the Historic Areas of Istanbul.
