 For centuries Bank Hall was the manorial home of a branch of the Banastres, lords of the manor descended from the Norman Robert de Banastre, who built a motte and bailey castle at Prestatyn in about 1164.In 1167 the Banastres fled when Owain Gwynedd, Prince of North Wales, destroyed the castle and the family escaped to Cheshire and Lancashire.In 1315 Sir Adam Banastre, who had extensive landholdings elsewhere in the county, led the Banastre Rebellion against Thomas, 2nd Earl of Lancaster, and was summarily beheaded at Charnock Richard when the rebellion failed.
