Stade Vélodrome Old Configuration (Marseille)

Before its 2014 renovation, the old Stade Vélodrome was a nightmare of exposed seating, forcing fans to endure brutal Mistral winds, rain, and scorching sun with zero protection. This design failure caused an estimated 40% of spectators to abandon their seats during matches in poor weather, making simple attendance an endurance test. The unprotected layout is particularly disastrous compared to the #2-ranked Fisht Olympic Stadium's enclosed design, which at least shielded its sparse crowds from the elements during the 2014 Games.
