The Gradeshnitsa tablets (Bulgarian: Плочката от Градешница) or plaques are clay artefacts with incised marks.
They were unearthed in 1969 near the village of Gradeshnitsa in the Vratsa Province of north-western Bulgaria.
Steven Fischer has written that "the current opinion is that these earliest Balkan symbols appear to comprise a decorative or emblematic inventory with no immediate relation to articulate speech."
"[1] The tablets are dated to the 4th millennium BC and are currently preserved in the Vratsa Archeological Museum of Bulgaria.
