A weathervane is a revolving pointer to show the direction of the wind, typically mounted on top of a building. Our custom copper weathervanes are the perfect finishing touch to your homes exterior. It points in the direction the wind is blowing from! So if the wind is blowing from the north. The wind vane would point toward the north, and the windsock would point south. No country home, workshop or barn is complete without a weathervane atop a cupola.
