- Sultanahmet Square 

Sultanahmet Square is located in Istanbul’s historic peninsula and is surrounded by significant structures from the Byzantine and Ottoman eras. In ancient times, this area was known as the Hippodrome and served as a venue for chariot races and other events.

One of the square’s most remarkable monuments is the Obelisk of Theodosius, originally commissioned by Egyptian Pharaoh Thutmose III in the 15th century BCE. It was brought to Istanbul by Roman Emperor Theodosius I in 390 CE. Made of granite and decorated with Egyptian hieroglyphs, this obelisk is an ancient piece that has stood since the Byzantine period.

Sultanahmet Square is a popular attraction for both locals and tourists, offering a rich historical atmosphere.

- Sultanahmet Mosque (Blue Mosque)

The Sultanahmet Mosque, also known as the Blue Mosque, is located in Istanbul’s Sultanahmet district. It was built between 1609 and 1616 by Ottoman Sultan Ahmed I and designed by architect Sedefkar Mehmed Agha. The mosque is commonly called the "Blue Mosque" due to the blue Iznik tiles that adorn its interior.

With six minarets and a striking dome structure, the Sultanahmet Mosque is one of the finest examples of classical Ottoman architecture. It serves both as a place of worship and as one of the city's most popular tourist attractions.
