Crystal Palace Football Club is a professional football club based in Selhurst in the Borough of Croydon, South London, England, who currently compete in the Premier League, the highest level of English football. Although formally created as a professional outfit in 1905, the club's origins can be traced as far back as 1861, when an amateur Crystal Palace football team was established at the Crystal Palace Exhibition building, which has led to claims by the club that Crystal Palace should be recognised as the oldest professional football club in the world,[1] after historians discovered a direct lineage through their ownership under the same Crystal Palace Company.[5][6] Both the amateur and professional clubs played inside the grounds of the Palace, with the professional club using the FA Cup Final stadium for its home games until 1915, when they were forced to leave due to the outbreak of the First World War. In 1924, they moved to their current home at Selhurst Park.
