Via cava

The via cava (Latin for "hollow way") refers to a sunken road or hollow lane. It is a type of road or path that is significantly lower than the land on either side, often formed over many years by erosion from foot traffic, animal traffic, or the passage of vehicles, and sometimes aided by deliberate construction. These roads can appear as trenches or deep grooves in the landscape.

Viae cavae are often associated with historical routes and landscapes, particularly in areas with soft or easily eroded soils. They can be important features in archaeological surveys, as they can indicate the presence of past settlements, trade routes, or agricultural land use. The depth and width of a via cava can sometimes provide clues about its age and the intensity of its use over time.

The term is sometimes used interchangeably with "sunken lane" or "hollow way," although the Latin term "via cava" lends a more formal or academic tone, often used in historical or geographical studies.
