Sighignola is a mountain of the Lugano Prealps, located on the border between the Italian region of Lombardy and the Swiss canton of Ticino.

[1][3] The eastern, Italian, slopes are relatively gentle, and the viewing terrace can be reached by road from Lanzo d’Intelvi, a frazione of the Italian comune of Alta Valle Intelvi, to the east.

However, the lakeside below the mountain is occupied by the Italian exclave of Campione d'Italia.

[1] In 1969 it was planned to construct a cable car from Sighignola, across the Swiss upper slopes, to Campione d'Italia.

Whilst construction was started, the cable car never opened, and in 2009 an agreement was reached between the Italian and Swiss authorities to remove the remains of the cable car structure.
