The Hagia Sophia of Istanbul: A Stunning Roman Ruin

Interior of the Hagia Sofia, Istanbul

There’s a reason why the Hagia Sophia (or Hagia Sofia) is so evocative of all of Istanbul. It’s a microcosm of the city’s entire history, from Roman origins to Ottoman Islam to today’s (relatively) secular nationalism. 

DSC_0235The site initially held an ancient temple, some remnants of
which remain in the current structure — like the dolphin design on the column to the right.

The first Christian cathedral was built
on the site in 360 A.D. It was rebuilt twice, both times after being destroyed by riots. (To see what the older Hagia Sophia(s) would have looked like, check out Byzantium 1200’s digital reconstructions).

The current building, which dates back to 537, was the largest church in the Roman empire. It also remained the biggest cathedral in the world for almost a millennium, beat out only by the Seville Cathedral in 1520.

In 1453, with Constantinople’s seizure by the Ottomans, the Hagia Sophia was turned into a mosque. And in 1935, at the height of Turkey’s secularization under Ataturk, it became a museum.

See what I mean about it being a microcosm of Istanbul — and Turkey — in general?

You could write a book on the Hagia Sophia. (Many have). But among the many treasures not to miss are its gorgeous Byzantine mosaics, which date back as far as the 9th century. Also
make sure you check out the seraphim (above) who was only recently uncovered. Although
his three compatriots are still plastered over, his face was revealed in 2010 after
being hidden for centuries by the Ottomans.

Coronation disk of the Hagia Sofia, IstanbulFor a clear tie to the city of Rome, meanwhile, look no further than the gray granite disk set into the floor, on the right of the middle of the church (left). Placed here by Justinian in the 530s, this is where the Byzantine emperors knelt to be crowned as early as 641. If you’ve visited St. Peter’s Basilica, you know that the Roman basilica boasts a similar disk in red porphyry. That’s the rota porphyretica, set into the old St. Peter’s Basilica and the spot where the pope crowned Charlemagne as Holy Roman Emperor in 800.

The similarity in the two stones is no mistake. Charlemagne was setting himself up in direct opposition to the “other” successors to the Roman empire, the Byzantines. By crowning him, Pope Leo III was showing that the papacy had wriggled from Byzantine control and was choosing the Holy Roman Empire as its protector instead. It’s also no mistake that the St. Peter’s Basilica disk is red porphyry, a precious stone that “one-upped” its sister stone in the Hagia Sophia. (Take that, Byzantines!)

On a broader, architectural note, of course, it’s no surprise that the Hagia Sophia looks — almost — reminiscent of that seemingly divinely-inspired building in Rome: the Pantheon. Both structures innovated in setting a circular dome on a square, rather than circular, shape. And both awed contemporaries by building domes on such a large scale. The Hagia Sophia’s original dome, which collapsed in 559, was thought to be slightly bigger in diameter but shallower than the current one, built in 563. Even so, the Hagia Sophia’s dome today is 102 feet in diameter — just 40 feet smaller than the Pantheon’s. (Check out the difference between the two in the images, below).

Don’t miss the garden of the church, either. There, in an unassuming tumble that reminded me of abandoned bits of column in Rome’s Forum, lie several marble blocks from the second church, dating back to 415. The most striking among them depicts twelve lambs, each symbolizing one of the twelve apostles. Many more remnants of the ancient church remain in the area — but they’re still buried underneath the ground, excavations ending in the 1930s after it was realized that continued work could harm the current structure.

Even without that, though, there are enough treasures in the Hagia Sophia to keep a history or archaeology geek satisfied — and maybe a little bit awed.

The Ancient, and Roman, Ruins of Istanbul

Istanbul's basilica cistern is one of the ancient Roman ruins of Istanbul

At first glance, Istanbul appears anything but a city tied to ancient Rome. Mosques and minarets, not ancient temples, dot the Turkish capital’s skyline. Its forum is hard to find, most of its imperial monuments long gone.

For a city that became part of the Roman empire in 73 A.D., and was turned into the capital, and dubbed “Nova Roma,” by Constantine in 330, it can seem surprising. But to find hints of the city’s classical past, you have to look more closely.

Searching for Roman ruins in Istanbul? Here’s where to find them. I’ll post this in two sections, so look out for the second installment tomorrow (here it is!).

Medusa column, basilica cistern, Istanbul

1. The basilica cistern. Even if you’re not all that interested in Istanbul’s ancient ruins, the cistern (shown above) is a must-see, if only for its eeriness: Descend down 52 stone steps, and you’re suddenly in a
cavernous chamber filled with ancient columns, each lit with a dim light, echoing
with splashes, the whispers of tourists, and (unfortunately, I think) “atmospheric”
music.  

The cistern was built by Emperor Justinian I in the early 6th
century, on the same spot as a basilica that had been first built by
Constantine two hundred years earlier. More than 105,000 square feet in area
and capable of holding 100,000 tons of water, the cistern provided water
filtration for Constantinople’s palace. More than 7,000 slaves were used to
construct it.

And all of those columns holding it up? There are 336 in
total, and they’re all ancient, too—most of them taken from even older structures
elsewhere in the empire. (Sound familiar? That kind of recycling is something
Rome, too, is known for, from the ancient Egyptian obelisks that dot the city
to, later, the use of the Roman ruins themselves in Renaissance-era buildings
like St. Peter’s Basilica). Most of their origins are mysterious, but some—like
the two upside-down Medusa heads—are particularly intriguing.

2. Column of Constantine. Erected in 330 A.D. by Emperor
Constantine to commemorate his new capital, the 115-foot column would once have
been another 50 feet tall. It also boasted a statue of Constantine on the top,
carrying an orb with a piece of the True Cross. A sanctuary at the column’s
foot included a number of relics, including an alabaster ointment jar that
belonged to Mary Magdalene, the basket from Christ’s miracle of the loaves and
fish, and a statue of Athena from Troy.

That’s all long gone, and the column
isn’t quite as impressive today
. But there’s no beating it as a (conveniently central) reminder of how integral Constantinople
was to the ancient Roman empire.

Valens Aqueduct, Istanbul3. The Valens aqueduct. Spanning one of Istanbul’s main
thoroughfares, the aqueduct is such a matter-of-fact part of the fabric of
modern Istanbul that it’s easy to forget it’s an ancient ruin. But it is. Built
in 368 A.D. by Emperor Valens, the aqueduct once ran for about 3,200 feet. The
surviving section today, at 3,020 feet, is nearly as long—not bad for a 1,600-year-old
structure. Just as the popes in Rome restored ancient aqueducts, so, too, did the
Ottoman sultans in Constantinople, meaning the aqueduct remained the city’s
main distributor of water through the Middle Ages. 

Serpent Column with the Obelisk of Theodosius in the background, Istanbul4. The Hippodrome. You could walk right through
Istanbul’s ancient hippodrome—built for chariot races by Emperor Septimius
Severus in the early 3rd century, and restored and enlarged by
Constantine 100 years later—without realizing it. Today, all the seats and
most of the structures are long-gone. The only hint you have that the site once was a
stadium able to hold 100,000 spectators is in the shape and dimensions of
Sultanahmet Square, which more or less follows the lines of the ancient circus.
(Just as Piazza Navona in Rome today has the same shape as Domitian’s first-century
Circus Agonalis).

But some monuments do remain. Perhaps the
most evocative is the Serpent Column, brought by Constantine from
the Temple of Apollo at Delphi. Also known as the Plataean Tripod of Delphi, the
column was cast in 479 B.C. to celebrate the Greek victory over the Persians. Persian
armor and weaponry was melted down for the column, and all of the names of the
Greek city-states that fought in the battle were etched into the sides. A gold
tripod, later lost, initially sat on top, supported by three serpent heads.

For a visual of what the chariot races once would have
looked like, the Obelisk of Theodosius is a must-see, too. The obelisk itself is
actually ancient Egyptian, dating to the reign of Tutmoses III around 1450 B.C.
In Alexandria until 390, it was moved to Constantinople by Emperor Theodosius
I. Underneath, a marble pedestal shows scenes including the chariot race
itself, and Theodosius giving the winner the laurel crown of victory. And then
there’s the typically-imperial inscription in which the emperor lauds none
other than himself—in this case, for supposedly moving the obelisk and
re-erecting it in just 32 days.

Off to Istanbul, the Other Rome

You can visit Rome, tour the forum, Pantheon and Colosseum, even visit the Baths of Caracalla, Hadrian’s villa at Tivoli, and the ancient aqueducts — and you still won’t get a full sense of the Roman empire.

The only way to do that is to visit Istanbul, founded as Constantinople — the new capital of the ancient Roman empire — in 330 A.D.

When people say the Roman empire “fell” in the 5th century, they’re wrong. The eastern half soldiered on. It was later dubbed the “Byzantine empire” by historians who wanted to make a nice, clean break for the timeline… but those living in Constantinople at the time would have considered themselves Romans.

Constantinople continued as the empire’s capital for nearly another millennium. And many traces of the city’s Roman past still remain. Both the Hagia Sofia and basilica cistern, two must-see sites, were built in the 6th century by Emperor Justinian, who wanted to bring the Roman empire back to its former greatness and reconquer the western half. Then there’s the hippodrome built under Emperor Septimius Severus in the 3rd century, and Constantine’s inaugural column of 330, and the classical sarcophagi, mosaics and other artifacts of the Archaeological Museum.

In a sense, Istanbul is Rome, its successor and its heir. I’ll be traveling through Turkey for the next week, and as I go, I’ll be posting about what to do, see and eat. Please enjoy this brief break from the eternal city. I’m sure I will!
