"Made of Stone" (aka "Wie aus Stein") is a song written for the 1999 (German) and 2014 (English) stage adaptions of Disney's 1996 animated film The Hunchback of Notre Dame, based on the book of the same name by Victor Hugo.
[4] In the context of this version of the musical, this song is the 11 o'clock show stopping number[5][6] and "major anthem",[7] taking place just before the finale while Quasimodo watches Esmerelda be burnt at the stake.
He is angry that they gave him bad and naive advice and realises that his master's words were harsh but true: the world is cruel and wicked.
He defeatedly concludes that he no longer wants to know what's "out there", and wishes that he, like the gargoyles, were made of stone so he wouldn't be able to feel the pain anymore.
[13] New Jersey Stage thought the song invites a performer to approached the piece with "detailed, nuanced delivery, and outstanding vocal".
