 The chapel had reinforced walls and formed part of the inner bailey wall, and was located at the southern end of the terrace next to the old stable block.When Henry de Lacy (c.1251–1311) gave Whalley to the monks of Stanlaw (Whalley Abbey), he withheld the chapel and its district.In 1334, the Abbey entered a legal battle for control over it, finally purchasing the advowson from John of Gaunt in 1365.
