In 1997, Arsenal started exploring the possibility of relocating to a new stadium, having been denied planning permission by Islington Council to expand its home ground at Highbury. After considering various options, the club bought an industrial and waste disposal estate in Ashburton Grove in 2000, winning the council's approval which manager Arsène Wenger described as being the "biggest decision in Arsenal's history" since the board brought Herbert Chapman to the club in 1925. Relocation began in 2002 but financing difficulties delayed work on the stadium until 2004 when Emirates Airline was announced as the main sponsor for the stadium which was completed in 2006 and cost £390 million.
The stadium has undergone a process of "Arsenalisation" since 2009 with the aim of restoring Arsenal's heritage and history. The ground has hosted music concerts and international fixtures featuring Brazil.
