May-Pole

The May-Pole was a unique glowing one from Fallout 4 concept art.

Background
The May-Pole would have stood at a terrifying height, akin to 300 feet, designed to look like a "melting elemental of agony." He would have been followed by hordes of mindless, regenerating feral ghouls.

Behind the scenes

 * The May-Pole was a passion project of character artist Jonah Lobe, who revealed its existence in a Reddit AMA. He stated that his main inspirations were Shadow of the Colossus and "Walking Man" by sculptor Alberto Giacometti. Although a model was created, the May-Pole never made it in the final game because of the technical issues it would have created.
 * The name of the creature referred to the maypole, a long pole traditionally used for people to dance around while holding long ribbons attached to the top. Similarly, the May-Pole was planned to be tall with feral ghouls running around the feet of the creature.
