In stonework, what is a primary function of cobblestones?

The primary function of cobblestones is to create walkways. Historically, cobblestones have been used in pavement construction for roads and pathways due to their durability and ability to withstand foot traffic and vehicle weight. They provide a stable, level surface that enhances pedestrian access and mobility. Cobblestones are often used in historical and decorative applications, contributing to the aesthetic appeal of urban spaces.

While other functions, such as supporting loads, improving drainage, or providing insulation, have some relevance in various contexts of construction, the main purpose of cobblestones is to create safe and navigable paths for people. This practical application aligns with their widespread use in both historical and modern settings.
