Bestival was a four-day music festival held in the south of England. The name Bestival is a portmanteau of the words best and festival. It had been held annually in the late summer since 2004 at Robin Hill on the Isle of Wight. In 2017 the festival relocated to the Lulworth Estate in Dorset. The event was organised by DJ and record producer Rob da Bank along with his wife Josie and was an offshoot of his Sunday Best record label and club nights. The initial Bestival attracted 10,000 people, growing to 50,000 in its final year, 2018. Bestival won 'Best Major Festival' at the 2015 UK Festival Awards, having won 'Best Medium-Sized Festival' in 2005, 2006, 2007 and 2009, 'Best Major Festival' in 2010, 2012 and in 2015, 'Fan's Favourite' in 2011 and 'Best Innovation' in 2005.
