Stock Photo - 05 July 2022, Saxony, Grimma: Two firefighters close one of the protective gates in the flood protection wall on the Mulde River as part of an inspection. 20 years ago, on August 13, 2002, the Mulde flooded the old town at a height of up to three and a half meters. One person died, 45 houses were destroyed, and the damage was estimated at 270 million euros. 20 years later, a flood protection system built at immense expense protects the city. A total of 78 closure units and two mobile flood protection systems then sealed off the more than two-kilometer-long wall. Photo: Jan Woitas/dpa. - Grimma/Saxony/Germany
