Hermitage of Santa Caterina del Sasso (Italian: Eremo di Santa Caterina del Sasso) is a Roman Catholic monastery located in the municipality of Leggiuno, in the Province of Varese and the region of Lombardy, Italy.

The monastery can be reached on foot by descending down a long winding stairway or by taking an elevator or by a number of ferry services or boats that dock at the pier.

You get the best view of Santa Caterina from the ferry boat on the Lago Maggiore, and the first thing you see is that the monastery consists of three chapels.

Albertus Besozzi founded Santa Caterina del Sasso, a wealthy cloth merchant who survived a violent storm at sea.

The first chapel, the chapter house, was extended by an additional floor in the 17th century, and the famous frescoes of the great crucifixion got heavily damaged.
