In his honor, the as yet unclimbed Sasso di Levante in the Langkofel Dolomites was renamed Grohmannspitze in 1875. The west peak of the Kellerspitzen in the Carnic Alps, which he first-ascended in 1868, is also known as Grohmannspitze. Already in 1898, 10 years before his death, the town of Urtijëi erected a monument to honor his many first ascents in the Dolomites. Since 1984 there is a Grohmann street in Vienna's Donaustadt district.
