This was some years ago, but you can ask your travel/tour guys about it. It's where Mary died. There was no body of hers, of course, since she was assumed into Heaven.
I shed TEARS there. I don't know why. It's not the most beautiful place on the planet, but it's her last place on earth. "Mary's house" is there too, where John took her those days of his missionary travels to spread The Word. It's a very simple, one-room stone house.
It was most moving. I hope you get to see it one day. Turkey has many things to see. You can also see the huge mosque that was once a huge Catholic cathedral. It's all mosque-like now but they keep a small corner of the place just for us tourists to see how MAGNIFICENTLY those early, early (6th century) Christians built their churches...Orthodox Catholic Churches: Hagia Sophia
From Wikipedia From the date of its construction in 537 until 1453, it served as an Eastern Orthodox cathedral and seat of the Patriarchate of Constantinople, except between 1204 and 1261, when it was converted to a Roman Catholic cathedral under the Latin Empire. The building was a mosque from 29 May 1453 until 1931. It was then secularized and opened as a museum on 1 February 1935.
Have seen pictures of that shrine in Turkey, Mary’s home. It is beautiful.
There are those who believed she assumed from there, and there are others who believed she went back to Jerusalem to both die and be assumed into Heaven from there. I believe more in the Jerusalem location, since more likely she wanted to be back where Her son did so much in that one week that brought about salvation.
