Here is an interesting coincidence!
I just found this article. It seems John the Baptist's Head is in a Church that was Converted into a Mosque where a flashpoint of Scripture prediction of this nation is now in the news.
Syria
"The head of John the Baptist thus was brought to Damascus where a thriving Christian Church was in existence, and the people all revered John the Baptist as a Prophet. The head of John was placed in an ornate gilded Sepulcher, in the Church that became known as the "Cathedral of Saint John the Baptist."
This building changed hands several times during the centuries, and in 1966 the Umayyad was a Muslim Mosque, and still held the Shrine; allegedly with the Head of John, when I personally visited the Mosque. Certainly my Muslim guide asserted that it was there, but no one questioned the fact that this was indeed the shrine of the head of John the Baptist."
Interesting to say the least.
