Cobblestone refers to naturally rounded stones that were historically used for paving streets and walkways. These stones are typically larger than pebbles and smaller than boulders, making them ideal for creating durable surfaces. Cobblestones are often made from materials like granite, basalt, or limestone, and their uneven shapes provide a unique aesthetic. In many historic towns and cities, cobblestone streets are a charming reminder of the past. They were commonly used before the advent of asphalt and concrete, and today, they are often preserved for their cultural significance. Cobblestone paths can still be found in European cities and are popular in landscaping for creating rustic outdoor spaces.
