The concrete separation wall that runs along the northern edge of Bethlehem is both a heavily contested political reality and one of the world's largest open-air galleries. Since Banksy's influential paintings in 2005, the wall has attracted artists from across the world; the Bethlehem section is particularly dense with murals, stencils, and political messages.
The stretch near the Walled Off Hotel and Aida Camp has the highest concentration of notable work. Walking the wall takes about an hour. It is a striking and often distressing experience — the artwork does not soften the concrete, razor wire, and watchtowers, and was not intended to.
