An Occupy Chicago activist watches as Chicago Police block the entrance to a Bank of America branch as about 50 protesters gathered outside, as part of a May Day demonstration, Tuesday, May 1, 2012, in Chicago.
Monday marks the one-year anniversary of Occupy Wall Street, and Chicago's branch of the anti-corporation group didn't let the milestone pass unseen.
Demonstrators gathered at 5:30 p.m. at Congress Parkway and Michigan Avenue for a 6 p.m. march expected to end at Jackson and LaSalle, where members rallied and spoke out about the movement.
"We have stood alongside the vulnerable, the righteous, and the brave in our efforts to build a better world," Occupy Chicago wrote in a statement on its website. "Together, we have created a community."
The group has marched alongside Chicago teachers as they hit picket lines after walking out last Monday, though the protesters mostly have disappeared from headlines since the NATO Summit wrapped up in the Windy City.
More than 30 cities, including Chicago, planned marches and rallies Monday to mark the anniversary.
Several hundred protesters from Occupy Wall Street staged a rush-hour sit-in near Trinity Church as scores of police officers on horses and in riot gear guarded the New York Stock Exchange. More than 100 people were arrested as of noon Monday, according to the National Lawyers Guild.
