Manic Street Preachers said of the spot: "Festival No.6 is the only thing that could break our self-enforced two-year British gig ban.
"To be able to play in Sir Clough Williams-Ellis's iconic village is something of a dream for us. See you in September."
Manic Street Preachers' last release was 2011's career-spanning singles compilation National Treasures - The Complete Singles, which featured a cover of The The's 'This Is The Day' as its only new material.
Their last studio album was the previous year's Postcards from a Young Man.
Bassist Nicky Wire has teased that the follow-up will be called 70 Songs of Hatred and Failure - a play on The Magnetic Fields' 69 Love Songs.
