Crystal Palace's use of triangular corner flags at Selhurst Park this season is more than just a stylistic choice—it's a nod to a longstanding tradition in football. This custom, which allows the defending FA Cup champions to use triangle-shaped corner flags instead of the standard square ones, dates back to 1927 when Cardiff City first introduced it after their FA Cup win.

Historical Context The tradition is believed to have started with Cardiff City, the first and only Welsh team to win the FA Cup. Other clubs have since adopted this practice, although recent winners like Manchester United, Manchester City, and Liverpool have not. Leicester City, however, embraced the tradition during the 2021-22 season.

Regulatory Perspective The International Football Association Board (Ifab), which governs the laws of the game, does not regulate the shape of corner flags. This lack of regulation has allowed clubs to use the triangular flags as a symbol of their achievements.

Crystal Palace's Statement On their decision to use triangular corner flags, Crystal Palace stated, "After that unforgettable day at Wembley on 17 May 2025, we finally joined the winners' circle. The triangle flags are a simple but powerful reminder of that historic moment. From the stands, it might just look like a flag—but for us, it is a symbol of making history."

Conclusion The triangular corner flags serve as a lasting emblem of Crystal Palace's FA Cup victory, a tradition that connects the club to a rich history of football achievements. This practice not only honors the past but also inspires future generations of players and fans.
