Giovanni Pietro de Pomis was an Italian painter, medailleur, architect and fortress master builder. His works show a marked influence of late-Mannerism.

Eggenberg Palace in Graz, is the most significant Baroque palace complex in the Austrian province of Styria. With its preserved accouterments, the extensive scenic gardens, as well as some special collections from the Universalmuseum Joanneum housed in the palace and surrounding park, Schloss Eggenberg ranks among the most valuable cultural treasures of Austria. Eggenberg Palace is situated at an elevation of 381 meters on the Western edge of the city. Its architectural design and the still visible imprint of centuries of history continue to bear witness to the vicissitude and patronage of the one-time mightiest dynasty in Styria, the House of Eggenberg.
