Dozens of buildings, including Boathouse Row, Citizens Bank Park and Lincoln Financial Field will be lit gold in memory of Floyd.

“George Floyd should be alive with his family today and it’s incumbent on all of us to keep his memory alive,” said Mayor Jim Kenney. “His death represented the countless Black Americans tragically killed by police, and it catalyzed a long overdue reckoning about systemic racism in this country. This week, I urge all Philadelphians to reflect on the tremendous legacy he leaves behind and on how we can continue to work together to enact police reform and dismantle institutional racism.”
