This happens a lot. Also parts of the wall missing because of cave/river generation. Obviously this is caused by the order, in which terrain generation is performed.

I think, it also leads to floating orchard fences above a ravine like that.

... although, I must say, in this case, it looks quite fancy with the ravine inside the city and the lava glowing at night ... :-)
