Mold Castle

“Hidden in plain sight”

Overview of Mold Castle


The story of Mold Castle is a long and eventful tale about Lords, Kings and Princes. Unlike most myths, this narrative is one of nonfiction, even though it could easily be mistaken for a Netflix series about fierce battles between soldiers, knights and horsemen and their intrepid survival.


The story of Mold Castle begins hundreds of years ago, with a man named Robert De Montalt. Robert de Montalt, a Norman Lord, was directed by the Earl of Chester Hugh d’Avranches, to build a magnificent castle on a mound of earth that was the monumental Bailey Hill in 1072.


Lost in time, little remains of Mold Castle’s remarkable whirlwind past. Nevertheless, there once stood a grand fortress made of hard wood and stone perched on Bailey Hill. This glorious fort was distinctive in nature due to its unique positioning overlooking the vale towards the Alyn River. Mold Castle was fortified with inner and outer castle walls, otherwise known as a motte and bailey.


Over the years this legendary stronghold was home to Lords, Ladies, and powerful Kings such as Owain the Great, King of Gwynedd and for many years was known as Bailey Castle. Today, it is known as Mold Castle, a place hidden in plain site of a bustling historic town.


Although motte and bailey castles were popular during this historical era, many of them, including Mold Castle, decayed with the times, or perished into nothingness, leaving only the smallest traces of their pivotal existence.
