March 18 (UPI) — The city of Dublin, Ohio, unofficially broke a Guinness World Record by arranging more than 1,050 people into the shape of a massive shamrock.

The record attempt, organized by creative agency Cornett and Visit Dublin Ohio, took place at Riverside Crossing Park after the city’s St. Patrick’s Day parade on Tuesday.

Organizers said more than 1,050 people in green ponchos formed the shape of the shamrock, enough to break the current Guinness World Record for largest human shamrock, which was set by 815 people in Dublin, Ireland, in 2013.

“St. Patrick’s Day is already a big moment for Dublin, but we wanted to create something that people could literally be part of,” Scott Dring, president and CEO of Visit Dublin Ohio, told Marketing Communication News. “Seeing hundreds of people show up ready to form a giant shamrock together was a pretty magical way to celebrate the city’s Irish spirit.”

The record attempt must still be reviewed by Guinness World Records to become official.
