In February 1300/1 his son John Hastings (1262–1313), Baron Bergavenny, had licence to crenellate his "manor and town of Fillongley in Warwickshire".

Among the graves is that of Isaac Pearson, the uncle of the Victorian novelist George Eliot, who lived in Arbury nearby.

Fillongley Hall was built in the mid 13th century and was destroyed in a fire in 1929, with rumours at the time suggesting that this was purposeful arson by the owner to claim insurance money and settle his debts.

There were several historic public houses in Fillongley, most of which are now closed, including The Butcher's Arms, The Cock Inn, The Durham Ox, The Red Lion, and The Saracen's Head.

During the Second World War, an anti aircraft battery operated from Fillongley, near to Beckfield Lodge Farm, and the site has since been converted to stables.
