Old City of Jerusalem. It is a place of pilgrimage for Christians because it is considered to be the route taken by Jesus, carrying the cross, on his way to his crucifixion. Hence the name, which is Latin for the way of grief or of suffering.
There are 14 stations of the cross along the 500 metre route but they can be hard to spot. As can be seen from the photo on the card, normal everyday life goes on along it.
