Guernica

Guernica is a town in the Basque region of northern Spain, which was discovered to be hiding ETA terrorists before World War 2.

Following the leadership of Generalissimo Fransisco Franco, a coalition of German and Italian fighter jets bombed the hideout of ETA's number 2 man, Pablo Picasso.

In retaliation, Picasso painted a picture, which was so bad, the Spanish government banned it from their country. The communist liberals waited until Franco died to bring the abomination back to Spain in 1974.

Some people say Franco didn't die, but was forcibly removed and is still in hiding to this day.
