National Day in Switzerland is observed every August 1 and commemorates the anniversary of the country's foundation in 1291, when three Alpine cantons signed the Federal Charter of 1291, marking the event as Switzerland's birthday. This federal holiday features various celebrations, including bonfires, fireworks, and picnics. A notable tradition is the illumination of the Rhine Falls, which has been lit since the 1920s for special events and exclusively on National Day since 1966. Additionally, many Swiss partake in a farmer's brunch, enjoying local organic foods such as pies, fresh cider, smoked sausage, eggs, and crispy Röschti. The holiday attracts both locals and tourists, showcasing Switzerland's rich cultural heritage.
