adliegh Castle stands on a ridge of unstable land overlooking the Thames estuary and may have been closer to the water than it is today. The castle has become a ruin over time but small sections of it can still be visited.

Hubert de Burgh was the owner of several castles in the Welsh Marches including White Castle which is similar in design. In 1232 the Earl fell from power and the incomplete castle became the property of the King Henry III. the castle remained neglected for over a hundred years, until the reign of King Edward III who refortified the walls and built new towers in response to the threat of invasion from France. The last couple of centuries have seen land slips destroy sections of the towers and walls.
