World's largest weather vane < extra info. >

According to the Guinness World Records, the world's largest weather vane is a Tío Pepe sherry advertisement located in Jerez, Spain. The city of Montague, Michigan also claims to have the largest standard-design weather vane, being a ship and arrow which measures 48 feet tall, with an arrow 26 feet long.
A challenger for the title of world's largest weather vane is located in Whitehorse, Yukon. The weather vane is a retired Douglas DC-3 CF-CPY atop a swiveling support. Located at the Yukon Transportation Museum beside Whitehorse International Airport, the weather vane is used by pilots to determine wind direction, used as a landmark by tourists and enjoyed by locals. The weather vane only requires a 5 knot wind to rotate.

A Weather Vane or Weather Cock is an instrument for showing the direction of the wind. They are typically used as an architectural ornament to the highest point of a building.

Although partly functional, weather vanes are generally decorative, often featuring the traditional cockerel design with letters indicating the points of the compass . Other common motifs include ships, arrows and horses. Not all weather vanes have pointers.
The word 'vane' comes from the Anglo-Saxon word 'fane' meaning 'flag'.
