We’ve got the basilica cistern and the Hippodrome, the Column of Constantine and the Valens Aqueduct. But there are other not-to-miss ancient Roman (or Byzantine) sites in Istanbul, too. Below, three others not to miss — and one more (perhaps the most major!) coming tomorrow.

5. Walls of Constantinople. One line of fortifications was
built by Constantine in the fourth century; a second row of walls was added by
Theodosius II in the fifth century. Although they saved the city from some eleven
invasions, they couldn’t withstand the invention of gunpowder and the Ottoman
conquest of 1453. Remnants of both the walls remain visible along their
original lines. (To see what the walls would have looked like, check out the great reconstruction done by Byzantium 1200).

6. Archaeological Museum. If you’re searching for antiquities in Istanbul, there’s no missing the Archaeological Museum. One of the world’s preeminent archaeological collections, the museum is replete with some 60,000 artifacts from a swath of ancient empires, from Greek to Egyptian, Phoenician to Hittite — and yes, Roman too. Some of the stars of the Roman collection include a series of beautiful sarcophagi, including this tomb with elaborate carvings of the story of Phaedra-Hippolita, dating to the second century A.D. (left).

The museum’s absolute show-stopper, though, is a Hellenistic piece: the Alexander sarcophagus. Because photos simply don’t do it justice, I considered not posting one. But to give you an idea of what the piece looks like, here’s just one detail of part of the sarcophagus. Seriously, though: This is something you have to see in person.
Dating back to 332 B.C., the sarcophagus comes from Sidon, a successful Phoenician city-state that today lies about 25 miles away from Beirut. Despite the name, it belonged not to Alexander (we don’t think), but probably to Abdalonymos, who Alexander made the king of Sidon in 332 B.C. Alexander, though, is prominent on the tomb, immediately recognizable for his curly and once-blond locks. The scenes that sprawl across the sarcophagus — two war scenes, two hunting scenes — tumble with vigorous action and expression. Not until the Renaissance, more than 1,000 years later, would sculptors reach this level of skill. To top it off, the sarcophagus is still scattered with the paint traces of its once-colorful past, giving the viewer a real sense of how this piece — and all Hellenistic sculpture — would have looked. That’s pretty rare.

All of this leaves out, by the way, hundreds of other treasures in the museums: the Sarcophagus of the Crying Women, also taken from the necropolis at Sidon; animal reliefs taken from Babylon’s Gate of Ishtar, built by Nebuchadnezzar in the 6th century B.C.; and the Treaty of Kadesh, the world’s oldest known recorded peace treaty, signed in the 13th century B.C. by Ramses II and the Hittites. 

Not bad.

7. Hagia Eirene. A bit sightseeing-weary after three full days in Istanbul, I almost didn’t go into this church. But I’m glad I did. Today part of the Topkapi Palace, the Hagia Eirene (top of the post) stands on the oldest spot of Christian worship in Istanbul.

The first church, built here in the fourth century by Constantine, burned to the ground; the current one dates back to an 8th-century restoration. (Not bad, really, as far as longevity goes). And, incredibly, it somehow missed the Ottoman sweep of turning churches into mosques — meaning even its 8th-century mosaic, depicting a black cross, was left intact.

And it has nothing to do with St. Irene. Instead, its name meant
the “Basilica of Holy Peace.” (It was designed in harmony with the
“Church of the Holy Wisdom,” or the Hagia Sofia, and the “Church of the
Holy Apostles”).

There’s another major ancient Roman site in Istanbul that I’m still missing. Any guesses?

Check back tomorrow for the final installment of this three-post series.
