On top of all this Moriz von Kuffner was so fascinated by astronomy that he sponsored the construction, equipment and operation of an observatory on some of his real estate on the slope of the Gallitzinberg where at the time of its construction (1884-1892) the Wienerwald reached almost down into Ottakring. This Kuffner observatory is his most important surviving legacy. Kuffner named asteroids 242 Kriemhild and 243 Ida, by courtesy of their discoverer Johann Palisa.
