This paper deals with the finding history and composition of the Avarian graves from Szentendre (County Pest, Hungary) based on literary data and new archival records. These records are in the legacy of the famous Hungarian archaeologist Flóris Rómer. They allow the reconstruction of the composition and the situation of the graves, which were found in 1871 on the ground of a brick factory. In the study drawings and notes of Flóris Rómer about finds and graves from Szentendre are published. They are important sources of the Avarian graves from the early Avarian age and the autor gives an evaluation on they in the study.
