The
Dunantspitze (German for "Peak Dunant", 4,632 m), formerly called
Ostspitze ("Eastern Peak"), is a
peak of the
Monte Rosa Massif in the
Pennine Alps in
Switzerland. It is the second highest peak of the massif, after the
Dufourspitze (4,634 m) and the second highest summit in Switzerland, but its
prominence is only about 15 metres. At the time of its first ascent it was unclear which of the summits was the higher.
