The mayor's office hosted a public hearing at Brooklyn Borough Hall Tuesday on the issue of controversial monuments throughout the city.

Separate hearings are scheduled for each borough, and residents got a chance to voice their opinions to the mayor's advisory commission on art, monuments and markers. 

Everyone who signed up to testify received three minutes to share why they believe certain monuments or markers on city property -- not federal property -- should be removed or remain as is.

Controversy around certain monuments has been growing nationwide. In Manhattan, a Christopher Columbus statue has prompted debate. The mayor says he doesn't want to make a decision on its future without input from residents. 

Other controversial statues include one of Marion Sims in Harlem. The pioneer in gynecology experimented on slaves.
