Helm, Mountain summit at Carnic Alps border between Sexten, Italy and Sillian, Austria

Helm is a rounded summit of the Carnic Alps on the Austria–Italy border, reaching 2,433 metres. Its top holds the ruin of the Helmhaus, a hut built in 1889, and the surrounding slopes carry remains of military structures from the 1915–1918 mountain war.

The Helmhaus on the summit was built in 1889 by the Sillian section of the German and Austrian Alpine Club on land provided by the Sexten municipality. Unused during World War I, it passed to the Italian state in 1920–1925 and became part of the Alpine Wall defences. It later served as a customs post and was abandoned in 1980; in 2007 the South Tyrol and Austrian Alpine Clubs held a competition for its renewal, won by architect Johannes Watschinger.

On 27 July 1958, 53 young people from seven countries placed a cross with the "Lebender Christus" on the summit, made by Josef Tschurtschenthaler of Sexten, together with the Guardia alla frontiera. The Sagenweg fairy-tale trail and the Heimatweg, built for the 1809–2009 Tyrolean commemorations by Schützen volunteers from Sillian, Sexten and Innichen, cross the summit.

Two modern cable cars provide straightforward access from valley stations in Versciaco and Sesto, terminating at elevations around 2,000 meters (6,500 feet). Hikers should wear sturdy footwear and bring weather-resistant clothing, as mountain conditions can change quickly.

The abandoned Helmhaus on the summit was built in 1889 by the Sillian section of the German and Austrian Alpine Club on land given by the municipality of Sexten. After 1920 it passed to the Italian state and served as a customs post before being abandoned in 1980.
