City officials agreed to let protesters take over Daley Plaza during the G-8 and Nato summits next spring.
The city's public building commission first denied an anti-war group's application to hold the rally at Daley Plaza, but officials changed their mind and said the plaza will be open for public assembly, according to the Chicago Tribune.
The organization, known as the Coalition against Nato/G-8 War & Poverty Agenda, calls the switch a victory.
Mayor Rahm Emanuel this month acknowledged the summits will make for a busy, tumultuous time in Chicago. He even offered an apology to the prom-goers, brides- and grooms-to-be, and graduation revelers whose daily lives will be interrupted.
"I apologize upfront for any disruption," he said.
