In an attempt to portray what the plaza could become if it remains a public space, the Friends of Congress Square Park announced a summer series of events at the park at Congress and High streets.

They include concerts, dancing, a pancake festival, art-making for kids and adults and other activities.

“This is just one of the many things that the Friends of Congress Square Park are doing this summer to show that it’s possible to revitalize a public space that the city gave up on years ago,” Frank Turek, an organizer of the group, wrote in an email to media.

The Friends of Congress Square Park is leading an effort to reverse a City Council decision to sell a portion of the park to an Ohio developer. The friends organization opposed the sale, and has forced a citywide vote June 10.

The friends group has added benches to the park and recruited a food truck to serve lunch daily. It has cleaned the park and Thursday announced the summer entertainment lineup.

It begins May 29 at 6 p.m. with a local music showcase featuring A Severe Joy, Boyfriends and Leveret. On May 30 at 6 p.m., the Hadacol Bouncers and the Portland Swing Project will lead an evening of swing dancing.
