If you look at a map of Jerusalem, you can see the border between the western (Israeli) and eastern (Palestinian) parts. But in reality, there's nothing like that on the ground. It's simply that Arabs live in the east and Jews live in the west.

And it's not because of some peace and harmony situation. Israel has separated itself from Palestine with a massive wall stretching 703 kilometers (to be precise, 10% of it is an enormous 8-meter wall, and the rest is a fence with a 60-meter buffer zone). Plus, over 20% of the barrier doesn't align with the formal border. So if you're thinking about heading to Jerusalem, go ahead and book a place in the eastern part without hesitation. It's noticeably cheaper there and no Shabbat restrictions. The only hiccup is that Google Maps sometimes gives you dodgy routes between the two parts.

The actual border cuts deep into Palestinian territory. There are checkpoints there. Arabs get let through without any checks. Going the other way—you need to show your passport. And during escalations, they can close the crossing entirely.

Such a massive canvas for creativity couldn't be ignored by artists, including Banksy. There's a great write-up about it here.
