Flag of Derry

There is a LOT going on here. We've got the Celtic harp, a pensive skeleton, a red cross, a sword, a castle and a half flag's worth of pitch black void.

There are some rumors about the flag — that the castle belongs to native Irish chieftains around 14th Century or that the skeleton is a Norman knight who starved to death in the aforementioned castle's dungeons.

True or not this is a singular maximalist gem.
