After agreeing the naming rights with American Express, the stadium was built in 2011 for £100 million with a capacity of 22,500 spectators with a further £15 million being spent in 2013 to increase the capacity to 31,800. It is now the second biggest stadium in the South East of England and, after winning promotion to the Premier league in 2017, now stages Premiership football.

The stadium tour took an interesting, in depth look at the football pitch, terraces and technical area followed by a behind the scenes tour giving the group an insight into the history of the football club. The tour gave the 15 strong group intimate access to the dressing rooms, hospitality areas, the directors lounge, executive boxes and the high tech media centre.
