<human>:  I have a question about the Hagia Sophia (stanbul). What is the meaning of the name?
<bot>: The name of the Hagia Sophia is derived from the Greek words <unk> (hagia) meaning holy, and <unk> (sophia) meaning wisdom. The Hagia Sophia is a church and museum in Istanbul, Turkey. It was built in 537 AD and was originally a Christian church. It was converted into a mosque in 1453 AD, and then into a museum in 1935 AD.
