A bright orange peace sign appeared on a hillside on the Greek island of Lesvos on New Year’s Day.

The peace sign was made by gathering more than 3,000 life jackets discarded by refugees arriving on the island.

Dozens of Greenpeace and Médecins Sans Frontières (MSF) volunteers and local supporters participated in this initiative to create the massive peace sign on a hillside overlooking the small strait between Greece and Turkey that has become a main passageway for those fleeing to Europe, as Mashable reports.

The sign is a way to honor those who have made the journey and to urge peace in the new year, according to Greenpeace.

Those involved in the project are calling for safe passage to those fleeing war, poverty and oppression.
