[3] From the Early Middle Ages until the 16th century, Selzen belonged to the Worms Cathedral Foundation.
In the 15th century, the Electorate of the Palatinate acquired the chapel court and ousted the Worms Cathedral Foundation.
This action is reflected in the then court seal (and in the current coat of arms), with the blazon reading in part “the Palatine lion holds in the right paw the robbed Worms key”.
Such joy was brought by this that the elm at Selzen’s southeast corner was felled and the community had a bonfire.
According to a legend, in the Middle Ages, the villagers were obliged to keep the frogs in the Selz or in the pond quiet by striking the water with staves.
Selzen, as witnessed by the Frankish grave finds, grew together from three cores of settlement, the church in the east, the Worms tithe court in the northwest and the mill in the south, near which a stone path (1617) takes the footpath to Undenheim over the Selz.
