In July 2013, France experienced the worst heat wave since 1900. This was followed by thunderstorms that caused huge damage from Caen to Strasbourg. Everywhere, winds of over 62 miles/h (100 km/h), topped with hail, spread panic. The Verzenay mill, emblematic of the Champagne-Ardenne region, lost three of its wings, although they were firmly attached. The old grain mill built in the 19th century (1820) is still standing. A few months later, four new 9-metre-long wings, each weighing 1,543 lbs (700 kilos), were installed.
