Brightly coloured billboards, granite sculptures and a 75 metre mural at a sports park are among the artworks which will be part of the fifth Folkestone Triennial later this year.

Twenty artists have been announced for this year's edition of the Triennial, organised by Creative Folkestone, which is subtitled The Plot, and will run from Saturday, September 5 to Sunday, November 8.

Its theme, The Plot, asks visitors to consider the relation between stories and realities. Curator Lewis Biggs said: "Everyone becomes aware at some point of the gap between our lived experience and what is narrated about it. Sometimes this gap is so extreme that we assume it is the result of malice – it’s a plot. With conspiracy theories becoming ever more popular, it’s never been more urgent to think about the gap between the talk and the action, between our stories and our realities."

The artworks will be along three routes associated with particular stories: the streets associated with physician William Harvey, noted for his ‘discovery’ of the circulation of the blood; St Eanswythe’s Watercourse; and Folkestone’s industrial road The Milky Way.

Artists selected include Rana Begum, Sam Belinfante, Stephenie Bergman, Patrick Corillon, Shezad Dawood, Richard Deacon, Jacqueline Donachie, genuinefake, Gilbert & George, Helga Griffiths, Mariko Hori, Christopher Houghton Budd, Atta Kwami, Morag Myerscough, Jacqueline Poncelet, Pilar Quinteros, Mike Stubbs, Jason Wilsher-Mills, Winter/Hörbelt and HoyCheong Wong & Simon Davenport & Shahed Saleem / Makespace.

Rana Begum will create a special colour scheme for the replacement beach huts on Lower Saxon Way while sculptor Richard Deacon will create five new granite sculptures in Kingsnorth Gardens on currently empty platforms.

At the Harbour Arm, Atta Kwami, whose signature style uses colour and abstract painting style will look at place the traditional home-made street vending kiosks of West Africa in dialogue with local food-vending kiosks.

Co-commissioned by England’s Creative Coast, artist Pilar Quinteros presents Janus’ Fortress: Folkestone - a monumental sculptural head on a cliff top looking both outwards at Europe and inward to England, contemplating what connects us but what also divides us.

Gilbert & George, whose trademark designs are graphic style, photo-based artworks, will have their works plastered on billboards around the town.

Following the Triennial some works remain as permanent additions to what has become the UK’s largest urban exhibition of contemporary art.
