Flint Castle - painted by Turner and featured in William Shakespeare's Richard II
This castle, which overlooks the Dee Estuary, was completed by 1284 and its four towers still stand.
However, the castle was largely destroyed some time after 1646, following its fall to parliament during the Civil War.
It was here that the county of Flintshire was established, seven years after King Edward I ordered work to begin on Flint Castle.
The castle, formerly the site of bloody battles between the Celts and Romans, British and Saxons, Welsh and Normans, overlooks Wirral on the other side of the Dee.
Once it would have dominated the skyline. Today, it is overlooked by high rise flats in Flint town centre and from which the photo (top) was taken.
Famously, Flint Castle was painted by Joseph Turner in 1838 and featured in William Shakespeare's Richard II.
