The three peaks of Lavaredo, or the “Tre Cime di Lavaredo” in Italian, are three distinctive battlement-like peaks, in the Sexten Dolomites of northeastern Italy. They are probably one of the best-known mountain groups in the Alps, and one of the most photographed in Italy. The three peaks are named, from east to west, "little peak" (Cima Piccola), "big peak" (Cima Grande) and "western peak" (Cima Ovest). The Cima Grande has an elevation of 2,999 metres (9,839 ft). It stands between the Cima Piccola, at 2,857 metres (9,373 ft), and the Cima Ovest, at 2,973 metres (9,754 ft).
