This is one of the magnificent landmarks in Istanbul’s historical centre. The Hagia Sophia, whose name translates to “holy wisdom”, was built by the East Roman Empire in the 6th century. It was then converted into a mosque and fortified following Mehmed the Conqueror’s rule in 1453. You can admire this architectural wonder’s marbled structure, as well as its dreamy interiors. It features calligraphic panels and bronze lamps, and most of its walls are covered in beautiful mosaics made of gold, silver, and colourful stones.
