The Day of Negrest-Oas City is organized each year in August starting from the year 1998. In 2014, the local authorities changed the name of the event naming it “The Oas Heritage” and it became in this way a holiday of the cultural and ethno-folkloric heritage of Oas Country.
The holiday takes place in the middle of August when thousands of Negresti Oas people and Oas people that live abroad come back home. The event is a way to see the families, of celebrating the popular attire and the traditions from the area.
A handiwork fair, expositions of plastic art, concerts of popular music and contemporary music occur during the festival.
