 To the south, west of the road at the brook's steep bank and partly within Eßweiler’s limits, stand the ruins of the Sprengelburg (also called the Springeburg), a castle that was once the seat of the Lords of Mühlenstein, vassals to the Rhinegraves of Grumbach.Going by the many prehistoric archaeological finds in the broader area around Oberweiler im Tal, it may be assumed that the area right near the village was inhabited as far back as the Bronze Age and the Iron Age, and perhaps even as early as the New Stone Age.Currently, nothing is known about definite finds within Oberweiler’s limits.
