Here is a memorable list of famous buildings in Istanbul to add to your plans.
Famous Building in Istanbul: 4 Places to Start
Galata Tower

Galata Tower is in Taksim, and you can reach it on foot from Karaköy or Taksim Square. The Genoese colony built the tower for defense in the 14th century. They called it the “Tower of Christ,” and to see their traces you may join Galata-Genoese walks. During the Ottoman Empire, it was also used for the detection of fires.
Standing on one of the Istanbul hills like a mysterious guardian of the city, the tower has inspired both legend and history. A city legend says that if you visit Galata Tower with your lover, you will marry him or her. A real story linked to the tower is that Hezarfen Ahmet Çelebi flew from Galata Tower to Üsküdar by using his wing-like apparatus. Today, when you visit the tower, you can climb its terrace and enjoy one of the best views of Istanbul. There is also a restaurant, though it is wise to check the official site before your visit for current details.
Maiden's Tower
Maiden's Tower stands in the middle of the Bosphorus, and you can visit it by taking small boats from the Üsküdar seaside. It was built around 410 B.C. and used for many purposes, including as a defense tower and lighthouse.
According to an old legend, a Byzantine king built the tower for his daughter because she was cursed and would be killed by a poisonous snake. Sadly, the princess could not escape her fate, and a poisonous snake reached the tower hidden in a basket of fruit. You may spend your day in Üsküdar and finish it with a visit to the tower. There are museum and restaurant sections within the building, and the setting offers lovely views of the Istanbul sky and the busy ferries crossing the Bosphorus.
Hagia Sophia
Hagia Sophia is in the Fatih district, and you can go there by tram from Eminönü. It was built at the beginning of the Middle Ages and was used as a cathedral. According to a well-known legend, when Byzantine Emperor Justinian opened Hagia Sophia, he said, “Solomon, I have surpassed you,” referring to King Solomon and his enormous wealth as mentioned in the Bible.
During the Ottoman Empire, Hagia Sophia was used as a mosque and repaired many times. Today, it remains one of the most remarkable monuments in the city, famous for its magnificent atmosphere, huge dome, and wall figures and scenes from the Bible. When you visit the area, you can also see the nearby Blue Mosque, which has stood beside Hagia Sophia for many years. For broader historical context, you can also review the UNESCO overview of Istanbul’s historic areas at unesco.org.
Ortaköy Mosque
Visiting Ortaköy Mosque and taking a photo with its magnificent setting is a classic Istanbul experience. This mosque was built during the last centuries of the Ottoman Empire. At that time, the Ottomans were interested in Western art, and this building is one of the symbolic places where you can see traces of that interest.
The mosque has magnificent details and fine craftsmanship on its walls. Another reason it is so famous is its position right beside the Bosphorus. You can visit during the day or at night, and the area is lively with small shops selling souvenirs. If you are hungry, kumpir is a popular lunch choice, and Ortaköy waffle is a well-known dessert to try after your walk along the shore.
Why These Istanbul Buildings Stand Out
Discovering Istanbul starts in its lovely streets and continues through buildings that hold centuries of stories. Galata Tower tells the story of Hezarfen Ahmet Çelebi while offering a wonderful city view. Maiden's Tower welcomes visitors in the middle of the sea with the legend of the unlucky princess. Hagia Sophia appears almost like an old fairy-tale monument, carrying memories of Byzantine emperors and Ottoman sultans. Ortaköy Mosque stands gracefully by the Bosphorus, combining architecture, water, and daily life in one scene.
