I lost an argument on FR about whether Jerusalem was built on seven hills. Unknown to me, landscaping has rendered several of the hills indistinct.
I don’t think landscaping is the issue. Jerusalem has 4 at most, and probably just 3. The issue is whether they can count hills that are outside of Jerusalem.
I’d think they cannot. But, it’s the only way to get to 7.
Rome, on the other hand, has at least 7 hills inside the 100 AD city boundaries.
