Archaeological digs at several barrows within Weitersbach's limits have unearthed finely decorated ceramics, bronze weapons and pieces of jewellery.

These are grave goods from the prevalent culture about the year 500 BC, when Celtic settlers of Early La Tène times used the favourable location on the Idarkopf's south slope as their dwelling and farming place.

Near the main building stood drying ovens for grain and smoked foods: a clear hint that there were both extensive cropraising and significant livestock raising here.

The charge above the line of partition is a reference to the village's former allegiance to the Waldgraviate-Rhinegraviate and indeed is the heraldic device once used in the Waldgravial-Rhinegravial court seal at Rhaunen.

The corn oast is an archaeological artefact from the land of the Treveri (a people of mixed Celtic and Germanic stock, from whom the Latin name for the city of Trier, Augusta Treverorum, is also derived) that came from the old Roman villa rustica in Weitersbach.
