Cobblestone streets are roadways paved with small, rounded stones, known as cobbles. These streets were commonly used in Europe from the Middle Ages until the 19th century. The stones are often set in a pattern, providing a durable surface for foot and vehicle traffic. Cobblestones are typically made from granite, basalt, or other hard materials, making them long-lasting. Today, many historic towns and cities, such as Rome and Amsterdam, still feature cobblestone streets, adding to their charm and character. While they can be visually appealing, cobblestone streets can also be uneven and challenging for modern vehicles and pedestrians, especially those with mobility issues.
