The Hagia Sophia is an ancient structure that was built 

between AD532-AD537 as a Greek Orthodox cathedral 

in Constantinople, which is present-day Istanbul. It was 

converted into a mosque after the city was conquered by 

the Ottomans in 1453.

In 1935, this famous Turkish landmark became a museum 

and has since been open to visitors from all over the 

world. The interior of this historical site is covered in 

mosaics that depict the Virgin and Child and other 

religious figures.
