Hartera is an annual electronica music festival held in Rijeka, Croatia. The name derives from the festivals location, an old paper factory (which was one of the largest in Europe) that functioned for 150 years before shutting down. One of the original purposes of the Hartera Festival was to preserve the old building by converting it into a public gathering for cultural purposes.^[1]
