There are memorials to the dead and the living, to fallen heroes and the victims of racism and ethnic cleansing.
What does it mean to memorialize a people or group, and who gets to tell that story?
The debate over the future of George Floyd Square in Minneapolis offers insight into how memorials can provide a space for reflection.
The giant metal fist symbolic of Black Liberation, with its red, black and green striped flag flying high, continues to stand tall over the intersection where Floyd was killed by a Minneapolis police officer.
The George Floyd Global Memorial organization wishes to maintain the site as a sacred spacewhere people can "grieve, pay respect and be a voice for justice." More than 3,000 offerings of street art, drawings by kids, protest signs, flowers, letters and other gifts remain at the intersection.
Meanwhile, old statues across the United States have come down as the nation debates its history of racial injustice and genocide.
In Duluth last fall, city officials helped install a historical marker at the site where three Black men were beaten, tortured and lynched a century ago after being wrongfully accused of raping a white woman. A memorial wall with three bronze sculptures representing the men was erected there in 2003.
Africa's Sankofa symbol — a bird with feet pointed forward and head turned back — suggests that we should learn from the past. Artist Esther Osayande created such a work for George Floyd Square, but says the piece is not a memorial, but "an acknowledgment, an alert. Important information for the future."
