Monte Rosa (Italian: [ˈmonte ˈrɔːza]; Lombard:
Mont Roeusa [ˌmũː(t) ˈrøːza]; French:
Mont Rose [mɔ̃ ʁoz]; Walser:
de Gletscher or
de Gorner; German:
Monte Rosa) is a mountain massif in the eastern part of the Pennine
Alps 
, on the border between Italy (Piedmont and
Aosta Valley 
) and Switzerland (Valais). The highest peak of the massif, amongst several peaks of over 4,000 m (13,000 ft), is the
Dufourspitze 
(4,634 m, 15,203 ft), the second highest mountain in the Alps and western Europe, after Mont Blanc. The east face of the Monte Rosa towards Italy has a height of about 2,400 metres (7,900 ft) and is the highest mountain wall of the Alps.
The group is on the watershed between the Rhône and Po basins and has a topographic prominence of 2,165 metres (7,103 ft) which is ranked fifth in the Alps.
The Monte Rosa massif has four faces. Three are in Italy: the Liskamm heading above the Val de Gressoney; the Valsesian face above
Alagna Valsesia 
at the upper part of the Valle della Sesia; and the steep, big east wall above Macugnaga in the Valle Anzasca.
