Corniglia is a frazione ("fraction") of the comune of Vernazza in the province of La Spezia, Liguria, northern Italy with a population of about 150 (in 2016). Unlike the other localities of the Cinque Terre, Corniglia is not directly adjacent to the sea. Instead, it is on the top of a promontory about 100 metres high, surrounded on three sides by vineyards and terraces, the fourth side descends steeply to the sea. To reach Corniglia, it is necessary to climb the Lardarina, a long brick flight of steps composed of 33 flights with 382 steps or, otherwise follow a vehicular road that, from the station, leads to the village. Sometimes a small bus runs.
The village stretches along the main road, Fieschi Road, and the houses have one side facing this road and the other facing the sea. Corniglia is characterised by narrow roads and a terrace in the rock from which all other four Cinque Terre's villages, two on one side and two on the other, can be seen. The town planning structure presents original characteristics compared to those of the other villages: the houses are lower set, and only more recently higher, similar to those of the villages of the hinterland.
Corniglia is mentioned in a famous novella of Giovanni Boccaccio's Decameron and in the novel The Invisible Circus by Jennifer Egan.
