The National Day of Remembrance for the Victims of Forest Fires is observed in Portugal every year on June 17. This day commemorates the over 60 individuals who lost their lives and the more than 250 who were injured in the devastating wildfires of June 2017, which were the deadliest in Portuguese history. The observance was officially established in 2019 by the Assembly of the Republic to honor not only the victims of the 2017 fires but also those who have perished in forest fires throughout the country's history. On this day, the national flag is flown at half-mast to pay homage to the victims. The wildfires began in the municipality of Pedrógão Grande and were exacerbated by a heatwave, resulting in significant destruction, including over 500 homes. The day serves as a solemn reminder of the tragic events and the impact of forest fires in Portugal.
