If you’ve ever been to Istanbul—or seen the famous documentary film Kedi—you’ve probably noticed the many cats that live in and around the city’s historical sites.
Istanbul is a feline paradise, and they’ve made themselves at home in the most historic and breathtaking landmarks. From the heights of Galata Tower to the hidden corners of the Grand Bazaar, the cats of Istanbul are part of the story.
Let’s explore 30 of the most famous Istanbul historical sites… through the eyes (and paws) of its furriest locals.
Cats and their love for Istanbul’s historical sites: 30 must-see feline attractions
1. Hagia Sophia
Originally built as a cathedral in 537 AD, Hagia Sophia later became a mosque, then a museum, and now functions again as a mosque. It’s one of the most iconic buildings in the world, known for its massive dome, stunning mosaics, and the way it blends Christian and Islamic design elements. It’s a must-see, whether you love history, architecture… or cats.
Locals say the Ottomans welcomed the cats as natural pest control, but they’re royalty now.
The Hagia Sophia cat named Gli even became world-famous after Barak Obama made friends with him.
2. Topkapi Palace
This sprawling complex served as the heart of the Ottoman Empire for over 400 years. It includes imperial halls, jewel-filled treasuries, sacred relics, and lush courtyards. You’ll walk the same grounds as sultans, courtiers, and… a surprising number of purring residents. Their poised elegance fits right in with the grandeur of this former royal residence.
3. The Blue Mosque
Also known as the Sultan Ahmed Mosque, this stunning building is famous for its six minarets and beautiful blue İznik tiles. It’s still a working mosque, so dress respectfully and plan around prayer times—but it’s 100% worth it. The atmosphere is peaceful and deeply spiritual.

4. The Basilica Cistern
This massive underground reservoir was built in the 6th century to provide water to the Great Palace. Today, it’s a cinematic, lantern-lit space where water reflects the rows of ancient columns—including two with mysterious Medusa heads. It’s a unique experience that gives you goosebumps in the best way.
5. Galata Tower
This medieval stone tower was once part of the city’s defense system and later served as a fire lookout. Now, it’s a favorite for visitors wanting 360-degree views over Istanbul’s old city, Bosphorus, and Golden Horn. Get your camera ready—this is one of the best photo spots in town.
6. Süleymaniye Mosque
Commissioned by Sultan Süleyman the Magnificent and designed by the famous architect Mimar Sinan, this mosque complex is an architectural gem. It’s less crowded than the Blue Mosque, offers incredible views of the city, and has a wonderfully serene vibe.
7. The Grand Bazaar
With over 4,000 shops, the Grand Bazaar is a dizzying maze of colors, sounds, scents, and cats. This historic market has been the center of trade since the 15th century. You can find anything from spices and ceramics to carpets and gold jewelry. It’s chaotic, fascinating, and wildly photogenic.
8. Maiden’s Tower
Also called Kız Kulesi, this tiny tower has been everything from a lighthouse to a quarantine station. Today, it’s a romantic spot with incredible views and a small museum and café. Take a short boat ride and let the breeze (and cats) work their magic.
9. The Walls of Constantinople
Built in the 5th century, these massive stone walls once shielded Constantinople from invaders. You can walk sections of them today for a quiet, off-the-beaten-path look at the city’s layers of history. The views are great—and the cats are basically tour guides.
10. Yıldız Park
This lovely park stretches across a hillside between Beşiktaş and Ortaköy. It offers winding trails, duck ponds, and historic pavilions. It feels worlds away from the city bustle, but it’s just a quick walk from the waterfront. Bring snacks. Bring a book. The cats will find you.
11. Dolmabahçe Palace
This stunning palace overlooking the Bosphorus served as the administrative center of the Ottoman Empire during the 19th and early 20th centuries. The place is full of glittering chandeliers, grand staircases, and rooms so elegant they look like they belong in a fairytale. But the real surprise?
The cats lounge like royalty in the palace gardens, sunbathe on marble steps, and seem completely at ease surrounded by all that splendor. Many believe they’re descendants of feline companions from the palace’s heyday. Whether that’s true or not, they definitely fit the vibe.
12. Rüstem Pasha Mosque
Tucked away in a busy market district, Rüstem Pasha Mosque is one of Istanbul’s most underrated treasures. It’s famous for its detailed Iznik tiles that cover nearly every surface inside. It’s quiet, beautiful, and easy to miss—which makes finding it even more special.
You’ll often see a cat or two curled up in a corner of the Rüstem Pasha Mosque or wandering along the edge of the prayer area.
13. Yeni Cami (New Mosque)
One of Istanbul’s most significant Ottoman mosques might not be that new. It was completed in the 1600s—but it’s still one of the most important mosques near the water in Eminönü, right next to the Spice Bazaar. It has towering domes, beautiful stonework, and the constant rhythm of daily prayer.
Amid the flurry of worshippers and tourists, cats walk with calm purpose, making their rounds through the courtyards and prayer halls. Locals treat them like old friends, offering food and affection. Some even believe these mosque cats bring good luck.
14. Chora Church (Kariye Mosque)
Chora Church (now called Kariye Mosque) is a little out of the way, but totally worth the trip. It’s home to some of the most breathtaking Byzantine mosaics and frescoes in the world, depicting rich biblical scenes that have survived for centuries.
And while you’re admiring the golden tiles and detailed artwork, don’t be surprised to find a cat casually strolling by or sunning itself near the entrance. The quiet, reverent energy of the place seems to draw them in, and their presence just adds to the church’s contemplative charm.
15. Haydarpaşa train station
The Haydarpaşa railway station sits right on the waterfront on the Asian side of Istanbul and has long been a symbol of movement, travel, and connection. Even though it’s not fully operational these days, it still holds that romantic, old-school travel vibe—with a side of cats.
16. Spice Bazaar (Egyptian Bazaar)
The Spice Bazaar, or Egyptian Bazaar, is a sensory overload in the best way: rows of colorful spices, Turkish delights, dried fruits, teas, and souvenirs of all kinds.
And winding through the narrow aisles are many cats.
Vendors often feed them and even name them, so don’t be surprised if a local tells you a particular cat’s entire backstory.
These cats know the best napping spots behind baskets of saffron or on warm windowsills, and they bring a little pause and sweetness to all the hustle and bustle.
17. Istanbul University
The university of Istanbul is one of the oldest in the world, dating all the way back to 1453. Its massive gates and historic campus in the heart of the city make it an iconic stop for anyone interested in Turkish culture and education.
Cats totally run the place here. They lounge on lecture hall steps, sunbathe on old stone benches, and occasionally pop into classrooms. It’s like they’re honorary students, soaking up the knowledge and good vibes right alongside everyone else.
18. Valens Aqueduct
The Valens Aqueduct is one of Istanbul’s most impressive Roman structures. Built in the 4th century, it once carried water into the heart of ancient Constantinople.
Now, it’s a hangout spot for some of the city’s most daring cats. You’ll spot them perched along the ancient arches, surveying the city from above like furry little emperors.
19. Çemberlitaş Column
Right in the middle of Istanbul’s bustling Old City stands the Çemberlitaş Column (also known as the Column of Constantine), an ancient Egyptian obelisk brought to Constantinople during the Roman era. It marks the spot where the old Forum of Constantine once stood.
20. Süleymaniye Hamam
Part of the grand mosque complex built by the legendary architect Mimar Sinan, Süleymaniye Hamam has been offering traditional Turkish baths since the 1500s.
21. Beylerbeyi Palace
This magnificent Ottoman palace sits right along the Bosphorus on Istanbul’s Asian side. It was once a summer home for Ottoman sultans and is known for its gorgeous interiors and waterfront views.
22. Fatih Mosque
Named after Sultan Mehmed the Conqueror, Fatih Mosque is one of Istanbul’s most important religious sites. Built in the 15th century, it’s both a place of worship and a symbol of Ottoman power. Cats seem to love the calm, sacred energy here.
23. Pera Palace Hotel
The Pera Palace Hotel is pure old-world charm. Opened in 1892 to host passengers from the Orient Express, it’s welcomed everyone from Agatha Christie to royalty.
Inside the elegant lobby and velvet-lined reading rooms, cats are part of the scene. They lounge on plush chairs, totally in their element among the chandeliers and antique rugs. You can’t help but smile when you see them living their best lives in such fancy surroundings.
24. Rumeli Fortress
Built in the 15th century, Rumeli Fortress once guarded the Bosphorus against invaders. These days, it’s a historic site and park, with epic views and old stone towers to explore. It’s also a perfect hide-and-seek zone for cats and great place to learn a little history and enjoy a picnic.
25. Theodosius Cistern
This is one of Istanbul’s many underground water reservoirs. It was built in the 5th century to supply Constantinople with water. Now, it’s been beautifully restored and opened to the public as a quiet, atmospheric space.
26. Istanbul Archaeological Museums
This is a group of three museums that showcase a large collection of historical artifacts from various civilizations—from Greek statues to Ottoman tiles. You’ll find them tucked behind Topkapi Palace.
Several cats live on the museum grounds, and they seem very much at home among marble statues and ancient sarcophagi. Some even have names and little beds set up for them.
27. Golden Horn Park
Golden Horn Park stretches along the water on the historic Golden Horn inlet. It offers grassy paths, shaded benches, great city views, and a whole bunch of cats. Locals come here for their morning walks, kids ride bikes along the trails, and couples picnic under the trees. It’s the perfect spot to take a break from sightseeing, watch the ferries float by, and make a few furry friends while you’re at it.
28. Süleymaniye Library
This library is located within the Süleymaniye Mosque complex and holds thousands of old manuscripts, some dating back hundreds of years. Even just the smell of old books and polished wood gives off serious “time travel” vibes. The space feels peaceful and soaked in knowledge — perfect for slowing down and soaking it all in.
And because this is Istanbul, of course there are cats perched on bookshelves.
29. Küçüksu Palace
This charming waterfront palace on the Asian side of Istanbul looks like something straight out of a storybook. Küçüksu was once the royal family’s version of a summer house. It’s not as massive as some of the other palaces in the city, but the intricate decor, European flair, and pretty gardens make it feel dreamy and elegant.
30. Walls of Theodosius
These walls have seen a lot. Built in the 5th century to protect the city of Constantinople, the Theodosian Walls still stretch across parts of the city today — weathered, worn, and seriously impressive. Walking alongside them almost doesn’t feel real — like the kind of thing you’ve read about in history books but didn’t expect to still exist.
They’re especially magical in the early morning or right before sunset, when the light hits the stone just right. And naturally, cats are here too — perched along the ledges, tucked into gaps in the walls, or just lazily watching the world go by.
