1. Seven Hills

Did you know that Istanbul was built on seven hills? The ancient city was known as the Greek city, Byzantium, and grew into prominence as Constantinople when Constantine the Great chose to develop the city as the new Rome.
Ancient Istanbul was founded on seven hills, like the Roman capital, and surrounded by strong city walls. When the Ottomans took over the city, they continued to develop the city with grandiose buildings. As you take in the city’s panoramic skyline, try to spot the peaks!
2. Hagia Sophia

Hagia Sophia is considered one of the important structures built for worship for both the Christian and Muslim communities. It’s also known as the Church of Holy Wisdom or Divine Wisdom and Ayasofya in Turkish. Its multiple names reflect its illustrious history.
Constructed as a church in the sixth century, it was the symbol of power of the Byzantine Empire. When the Ottomans took over the city, the building was turned into a mosque and the original mosaics were covered over by Islamic medallions and minarets were added.
The building continues to change and evolve so spend some time soaking in its architectural and cultural splendor and be a witness to its colorful history.
3. Blue Mosque

Formally known as the Sultan Ahmet Mosque, it’s famous for its stunning interior that’s decorated with over 20,000 blue Iznik tiles. Take a closer look at the hand-painted designs on the rare tiles. This beautiful mosque was the ambitious project of Sultan Ahmet I and was built by the revered architect, Sedefkâr Mehmed Ağa.
4. Golden Horn

The famed Golden Horn of Istanbul refers to the strategic horn-shaped estuary that flows from the Bosphorus Strait to the heart of the city. Golden Horn plays an important role in the growth of the city as it forms a natural defense and harbor and it’s the hub of shipping and trade.
The best place to experience the action and scenery of the Golden Horn is from the monumental Galata Bridge that connects the old Istanbul to the new districts.
5. Walls of Constantinople and Theodosius II

When Constantine the Great moved the capital of the Roman Empire from Rome to Constantinople (Istanbul), he surrounded his capital with mighty walls. The defensive walls traced the outline of the city and protected the people from invaders and external threats.
The city walls were extended and further fortified when the city was ruled by Theodosius II. While sieges and natural disasters damaged the walls, some sections of the walls were repaired and you can still see surviving ancient walls in the Old Town.
6. Bosphorus Strait

The famous symbol of Istanbul, this mighty waterway has defined the city’s past and present. Connecting the Sea of Marmara and the Black Sea and separating the Asian and European continents, this strait is strategically located.
The lifeline of Istanbul, the Bosphorus has brought people, trade, and resources like fish to the city. Today, you can immerse in the beauty of the Bosphorus by hopping on a ferry that cruises along the scenic channel.
7. Topkapı Palace

Experience the lives of royalty in the Topkapı Palace. It was the opulent residence of the Sultan and the administrative and educational center of the Ottoman Empire. Walk through the imperial gates, sprawling courtyards, and grand pavilions and imagine the hustle and bustle of heydays.
A top highlight of the palace tour is the cloistered harem where you can get a glimpse into the hidden world of the Sultan’s wives and concubines and their interactions with the Sultan.
8. Istanbul Archaeological Museums

If you only have time for one museum, visit the Istanbul Archaeological Museums which houses world-class artefacts spanning Istanbul’s eventful past from the Byzantine to the Ottoman period.

Be dazzled by the kaleidoscopic mounds of spices, nuts, dried fruits, and lokum (Turkish delights), and stuff your shopping bags with Istanbul’s local produce.
11. Underground Cisterns

Istanbul is famous for being a city of surprises and it hides the ancient subterranean structures.
The underground cisterns are water reservoirs built during the Byzantine period to store water for the growing capital city. The cisterns are feats of architectural wonders as they were constructed deep underground with strong foundations of arches and columns.
Basilica Cistern, the largest surviving cistern, is open to the public and its star attraction is the dense network of 336 marble columns and two famous columns adorned with carvings depicting Medusa heads.
Another underground water chamber worth visiting is the Theodosius Cistern that provides an immersive experience with 360-degree projection mapping.
12. Süleymaniye Mosque

Süleymaniye Mosque, also known as the Mosque of Süleymaniye the Magnificent, sits on one of the highest Seven Hills. Commissioned by Sultan Süleyman I, this colossal mosque is crowned by four soaring minarets with 10 balconies, signifying that Süleyman was the tenth Ottoman Sultan.
Marvel at the ingenuity of the architecture and design as you stroll through the serene grounds of the mosque and visit the ornate mausoleums of Sultan Süleyman I and his wife Roxelana. The beautiful mosque is the masterpiece of Mimar Sinan, whom the locals called affectionately as “Sinan the Great.” The accomplished architect designed many buildings for the royalty and his tomb lies just outside the mosque.
13. Galata Tower

The medieval tower is a striking symbol of Istanbul’s new district. It has a tumultuous history that started in the Middle Ages; it was a fire watchtower, defense fort, barrack, and even a dungeon.
As you climb up the tower, learn how the building has been rebuilt and restored throughout the years. The best time to visit is before sunset as you’ll enjoy the spectacular views of the city: day view, sunset, and the sparkling city lights.
14. Pera Museum

15. Dolmabahçe Palace

Standing proud along the Bosphorus, Dolmabahçe Palace was commissioned by Sultan Abdül Mecit I who wanted a more modern residence than the Topkapi Palace. It’s the biggest palace in Turkey and the final home of the Ottoman royalty.
Designed by imperial architects, the glamorous Ottoman-European palace was costly and led to serious financial problems plaguing the declining Ottoman Empire.
16. Asia

Istanbul is nestled on two continents–Europe and Asia, and you can easily reach the Asian side via a ferry across the Bosphorus Strait or the Marmaray underwater train.
Wander through Kadıköy, a vibrant neighbourhood with a lively local market, restaurants, and boutique shops. Take a dolmuş, a shared local minibus, to Üsküdar, a historic town with charming local markets and mosques.
17. Sunsets

Istanbul is famous for spectacular sunsets. The historic city is like a painting and the changing hues of the skies enhance its magnificence. Watching the sunset over the iconic city skyline and the glistening Bosphorus Strait framing the two continents is a magical experience.
