A weathervane is a device used to indicate the direction of the wind. It typically consists of a rotating arrow or figure mounted on a pole or rooftop. Weathervanes have been used for centuries as a practical tool for farmers, sailors, and meteorologists to determine wind direction. They are also commonly used as decorative elements on top of buildings, adding a touch of charm and whimsy to the architecture. Weathervanes come in various designs, ranging from traditional roosters and horses to more modern and creative shapes. They are often made of durable materials such as copper, brass, or iron to withstand outdoor elements. Whether functional or decorative, a weathervane can be a unique addition to any home or garden, providing both practical information and aesthetic appeal.
