There's an amazing wealth and variety of graffiti left by pilgrims just at the entrance to the Church of the Holy Sepulchre. Let's take a quick look . . .

This Wikimedia Commons photo is great because it is annotated with a number of detail photos of graffiti on different parts of the entryway! Worth taking a look.

The most prominent graffiti are the dazzling patterns of crosses on the lower parts of the columns and doors:

But there are actually lots of inscriptions -- in Greek, Arabic, Italian, Armenian, Georgian, Syriac, and more!

In 1384 an Italian pilgrim named Piero Vendramini climbed to the top of one of the columns and painted his name very visibly in red

On the wall between the door and the closest column, an inscription in Georgian:
"The tomb of Christ, have mercy on Sopron"
