GREEK PARLIAMENT, ATHENS, GREECE - 2018/03/31: A participant dressed up in Greek traditional outfit seen dancing in front of the Greek Parliament. A total of 350 young people from all over the world traveled to Athens to take part in Hellenic Youth in Action, the forum of all new Greek descent, which takes place this weekend in Athens, in the framework of Olympics 2016-2018. On a specially designed wall, the participants left their prints, and in that symbolic way they gave their mark.
