Sultanahmet Meydanı from Istanbul, Turkey

This square bears some of the ambiguity of the meeting point of the Orient and Europe. This is not a single square, but rather two squares brought together and identically named. Between the Hagia Sophia and Sultan Ahmet Camii, known as the Blue Mosque, lies a square with a fountain at its centre, often called Ayasofya Meydani, although the official name is Sultanahmet Meydani. It is a market-garden, built on the spot which held the Augusteion, the Roman forum of Augustus. Paradoxically, the long square between the Blue Mosque and the Museum of Islamic Art keeps the name Sultanahmet Park, although it is less of a park than the neighbouring square. There is no place in the world that brings together so much history. The obelisk of Theodosius the Great is, in fact, Egyptian, and was brought here in 390, from Luxor. Sculpted in Aswan granite, it was built in 1490 B.C. for the Egyptian pharaoh Thutmose III. The serpentine column was brought in 324 to the temple of Apollo at Delphi, where it celebrated the victory of the Greeks against the Persians. Cast from the alloy of the Persian weapons and melted down by the Greeks, it is now 2500 years old. Another obelisk was built in the 10th century by Constantin VII. One must also add the “German fountain” built in 1900 to mark the visit of Kaiser Wilhelm II. Then, there is the Art Nouveau façade, with the Oriental features of the building, which is now houses the rectorship of Marmara University. The Blue Mosque and the Hagia Sophia define a side of the square. On the opposite side, the Museum of Islamic Art is found in the palace of Ibrahim Pasha, the vizier of Suleyman the Magnificent. A marble column marks the kilometre zero of the Eastern Roman Empire, still visible in the north-eastern corner of the square. And that is not all. The square is, in fact, the arena of the Roman hippodrome.
