The Avar period cemetery in Frohsdorf is located in eastern Austria in the area of the former western periphery of the Avar Khaganate. In a non-literate culture like that of the Avars, it is only possible to reconstruct everyday culture, including funerary rituals, through archaeological sources. Through archaeological field seasons from 2001 to 2011, we have been able to document numerous coffins and grave fixtures made of wood in inhumation graves. Burials in coffins seemed to be common practice. The coffins are preserved in different states, including wood residues and charred wood residues. In Frohsdorf, in contrast to many other investigated Avar cemeteries, we subjected these coffins and their wooden remains to a detailed analysis. Wood species analyses show a preference for a certain type of wood, namely oak. Based on the preservation status of the wooden remains the authors have developed a hypothesis concerning part of the funeral ritual at this cemetery.
