The tradition of using wrought iron in decorative fencing dates back to the Roman Empire, where blacksmiths forged iron into both functional and ornamental pieces. By the Middle Ages, wrought iron became widely used in Europe for gates, railings, and fences, often adorned with intricate designs that showcased the skills of the blacksmith. Each piece was unique, reflecting the style of the period and the individuality of the homeowner. This practice has continued through to modern times, where wrought iron fence ornaments are still handcrafted, blending traditional techniques with contemporary designs.
