The Top 10 Istanbul Historical Sites to See
Istanbul is a city at the intersection of Europe and Asia that has accumulated an impressive cultural experience in the last centuries. For more than 1500 years it has been the capital city of three of the largest empires in the world for Empire: the Byzantine Empire, the Roman Empire, and the Ottoman Empire. Istanbul has become a city-esque museum and a unique opportunity for tourists to experience the greatness of ancient ages. This guide aims to present the best historical sites in Istanbul, in order to inform the reader of the major role which was played by Istanbul as a capital of the two empires dividing the East and the West.
1. Hagia Sophia

To this day Hagia Sophia remains a symbol of this ancient history of Istanbul as a crossroad between Eastern and Western civilization. Originally built by Byzantine emperor Justinian in 537 as an authentic first great Christian basilica then becoming an Ottoman mosque after the conquest of Constantinople in 1453. It was later reinvented as a museum during the twentieth-century restoration, and then again in recent decades it has been reverted back into a mosque but is open to people of all faiths.
Visitors often marvel at the astounding dome that seems to float above, created through Byzantine engineering. Inside its vast interior is decorated with intricate mosaics depicting Christian iconography alongside Islamic calligraphy and symbols that display Istanbul's religious evolution. Don't miss its famous "Weeping Column", said to have healing powers, or mosaics depicting Christ, Mary Virgin, or Byzantine Emperors!
2. Topkapi Palace

Topkapi Palace stood upon a hill overlooking the Bosphorus Strait for nearly 400 years, and Ottoman Sultan Mehmed II built it as their residence and administrative center for nearly 400 years. A stunning example of Ottoman architecture with exquisite rooms, courtyards, and gardens for entertainment. Topkapi's halls tell tales of imperial life, power, and intrigue while its harem provides insights into their private lives as sultans shared it among themselves and their families.
This Palace is filled with treasures, from jewel-encrusted thrones to the Topkapi Dagger in its Imperial Treasury, to its "Harem" section which contains quarters for the Sultan's family and concubines as well as its "Sacred Relics Room which houses religious artifacts deemed significant - said to include what some consider Prophet Muhammad's sword - along with much more!
3. The Blue Mosque (Sultan Ahmed Mosque)

Just across from Hagia Sophia stands the Blue Mosque - one of the world's most stunning and historically significant mosques. Commissioned by Sultan Ahmed I in the early 17th century to rival Hagia Sophia in terms of grandeur and beauty, its construction featured thousands of blue Iznik tiles for an airy, tranquil appearance within. Now serving as both a place of worship and an Ottoman architectural marvel it features six towering minarets and cascading domes that add charm.
This exquisite interior, boasting over 20,000 hand-painted tiles, makes an unforgettable impression. The striking central dome, with smaller half domes encasing it and intricate calligraphy on the walls, highlights Islamic art at its best; while outside, a spacious courtyard and fountain serve as perfect spots for photos.
4. Basilica Cistern

Hidden from the tourist circuits, you can stretch your neck in Istanbul and glance down to the Basilica Cistern, an underground Byzantine water reservoir built in the 6th century. Known as the ‘Sunken Palace’ this subterranean wonder has a storage capacity of between 80, 000 cubic meters and contains 336 marble columns which include recycled material from the Roman era.

8. Dolmabahce Palace

Built during the 19th century along the Bosphorus shore, Dolmabahce Palace stands as an iconic representation of the Ottoman Empire's final phase and acceptance of European architectural styles. Commissioned by Sultan Abdulmejid I for use by him and subsequent Ottoman Sultans, Dolmabahce replaced Topkapi Palace as their residence; today its lavish interiors blend both Ottoman and European influences in grand halls and luxurious rooms that delight visitors to Istanbul.

10. The Wall of Constantinople

The Walls of Constantinople, also known as Theodosian Walls, were constructed during Emperor Theodosius II's rule in the 5th century to protect his city against invaders and lasted for nearly 1,000 years until their demise due to the Ottoman conquest in 1453. Today, remnants can still be seen all across Constantinople with sections still standing and accessible for exploration.
Visitors to Edirnekapi Gate will find some of the most intact sections of walls around them; here they can climb and stroll the ramparts for impressive views while passing towers and gates that once made up part of city defense lines. Among these towers and gates is the now-closed Golden Gate, known for providing Byzantine Emperors with an entranceway after victory had taken place - it offers visitors the unique chance to walk back through centuries of history while experiencing old city boundaries directly.
