Hawarden's earliest occupation is uncertain. Iron Age work is considered fairly likely, while possible Saxon remains are less certain. A Norman motte-and-bailey castle is definite. That castle was destroyed before Edward I's new construction reshaped the site. Most of the visible remains belong to this later phase of the Ring of Iron.
