The village of Dalberg arose in the Gräfenbach valley at the like-named castle at a rather arbitrarily chosen spot that was rather ill-suited for agriculture.

[1] The municipality's arms might be described thus: Azure a fess Or between three fleurs-de-lis of the same and charged with a cross moline sable.

The following are listed buildings or sites in Rhineland-Palatinate's Directory of Cultural Monuments:[9] The more than 500-year-old chapel, St.-Leonhard-Kapelle, is consecrated to Saint Leonard.

The master builders in charge of the project might well have been Philipp I (1428-1492) and Friedrich (1459-1506) of Dalberg, who also appear in historical records as the caretakers of the churches in Spabrücken and Wallhausen.

What decided this might well have been a certain fashion, but rather likelier was a longstanding reverence that the family of chamberlains, for Gerhard, Chamberlain of Worms, and his wife Margarete, the last of the Dalberg line from the family von Schöneberg, had endowed a Saint Leonard's Altar at Saint Martin's Church at Worms as early as 1331.

Dalberg's first clergyman, as far as is known, was a man named Nikolaus Vickis, who from 1500 to 1506 was likewise the altarist of Saint Valentine's Altar at the hospital in Oppenheim.

It could be that the remuneration for this post was low, for even the Michael Schmitt from Wallhausen that Wolff von Dalberg appointed in 1538 had already been working since 1536 as the altarist of Saint Margaret's Altar at Spabrücken.
