The coat of arms of the Rabatta family is carved in a wellhead that once stood at Dornberk Castle and now graces the park at Kromberk Manor. Originally from Tuscany, the Rabatta family entered the service of Emperor Charles IV and settled in Gorizia (Germ. Görz) in the fourteenth century. In the fifteenth century, they were enfeoffed the Dornberk seigniory, which remained in their possession until they became extinct at the end of the eighteenth century. In 1634, when the family was elevated to the rank of counts, its coat of arms was improved by adding elements of the extinct Carraresi family from Padua. Nonetheless, the wellhead (1663) from Dornberk only features their original coat of arms (wings above three-peaked mountain). After it was left to slow decay together with the castle, the wellhead was purchased in 1974 by the Nova Gorica Regional Museum at the initiative of Branko Marušič and transported to Kromberk Castle, where it still stands partially reconstructed.
