The world’s biggest Swiss flag

The world’s biggest Swiss flag, a massive 31 x 31 metres in size and weighing over 500 kg, is anchored to a majestic ledge near to Lucerne, Switzerland. In order to withstand the enormous gusts of wind and fluctuations in temperature, parent company Serge Ferrari made the flag out of the sort of high-tech fabric normally used for sophisticated textile facades. Serge Ferrari Tersuisse’s twisted filaments with a special yarn finish ensure that the world’s biggest Swiss flag can cope with the toughest of weather conditions thanks to its superior tensile strength and UV resistance.
