 After the Sunday market trade had moved to a nearby dock warehouse (Stanley Market), Quadrant Park started holding all night raves in the then-vacant space.A loop-hole in a Sefton council licensing law enabled Quadrant Park to be the only legal all-night rave in the UK, as the venue did not sell alcohol.Quadrant Park's main period of activity began in early January 1990 with a capacity of 2,400, Quadrant Park began focusing on house music in early 1990.
