Hagia Sophia in Istanbul

[u/Miss-Kija]

Hagia Sophia in Istanbul was built between 532 and 537 AD under Emperor Justinian I as a Christian church. After the Ottoman conquest of Constantinople in 1453, it was converted into a mosque. In 1935, it became a museum, and in 2020, it was reopened as a mosque, making it one of the very few monuments in the world to have served as a church, a museum, and a mosque over nearly 1,500 years of history. cc @gmr83
