BLOOMINGTON, Ind. (CNN) -- A piece of artwork hanging at Indiana University is now the center of a big controversy.

The painting in question is a 22-panel mural that depicts a Ku Klux Klansmen burning a cross.

It hangs inside Woodburn Hall on the Bloomington campus.

Hundreds of students have signed a petition asking school officials to take it down, but the university isn't planning to take it down.

University officials say the purpose of the mural is to educate - and the university will maintain a welcoming and inclusive environment for all.
