Prayer Wall.

From Wikipedia:

The House of the Virgin Mary (Turkish: Meryemana or Meryem Ana Evi, "Mother Mary's House") is a Christian and Muslim shrine located on Mt. Koressos (Turkish: Bülbüldağı, "Mount Nightingale") in the vicinity of Ephesus, in modern-day Turkey (7 km from Selçuk).

It is believed by many Christians and Muslims that Mary, the mother of Jesus, was taken to this stone house by Saint John and lived there until her Assumption into Heaven according to many Catholics or Dormition according to the Orthodox.[1]

The remnants of the discovered structure have been dated to 6th - 7th centuries, with parts of the foundation and coal found on the site dated to the 1st century.

The current chapel at the site is the result of a restoration work completed in 1950[citation needed], built on top of original remains, for making the site suitable for pilgrimage after it has been declared an official Catholic pilgrimage site.

The restored part of the chapel is distinguished from the original remnants of the structure by a line running in between, painted in red.
