Etymologically, Steinbrunn means the source of the stone. The town owes its name to a nearby spring Taufsteinbrunn whose name is "the source of the baptismal font."
There was an old manor house, called Schlössel which had the right to tithes and a chapel known as the name Apollonia St., near which there was a source of water and where there are Roman brick remains. This chapel is dedicated to St. Appoline. One might assume that before the region was Christianised, the site was dedicated to Apollo.This town, once much larger, was, before the Reformation, divided into two parishes. The location of the church of Saint Léger is also known under the name of Kirchhof.
