Flint Castle

'Built for war and domination"

Overview of Flint Castle


Although Flint as we know it today is a peaceful town with thriving businesses and interesting historical attractions in abundance, it was once an uninhabited, desolated land with no prior settlement. This changed with the arrival of Edward I.


The position of the low-lying land around today’s Flint was considered a disadvantage to many colonisers, but for King Edward I, the pros outweighed the cons. The erection of Flint Castle was the first of many constructed after the Anglo-Welsh war of 1277, which was the beginning of a long and eventful feud between an English King and a Welsh warrior Prince. Sister Castles built by the feared Edward I in his conquest of Wales include; Conwy Castle, Caernarfon Castle,  Rhuddlan Castle and the ever impressive Harlech Castle.


Edward I, who commissioned the construction of Flint Castle as a fortress in 1277, chose its location due to the numerous benefits of the nearby river. This historic waterway, known as the River Dee, allowed the castle structure to become a useful outpost for the importation and exportation of valuable goods. In addition to this, the River Dee estuary was only a days march from Chester and provided the king with easy access back to England. With boats providing safe passage when the tide was high and the ability to travel across the shallow water and marshes on foot, or by horse when the tide was low, the benefits of the castle’s erection and its location played a great role in helping Edward I conquer Wales.


Although the castle’s build was initially taken on by Richard L’Engenour, it was later assigned to the infamous master mason, James of Saint George in 1278. Under the supervision of this one-of-a-kind architect, the construction of Flint Castle accelerated considerably.


To accompany his extravagant architectural style, King Edward employed a large workforce from across England and Wales. Over 1,800 masons, builders and craftsmen worked and lived in or nearby Flint Castle for over 9 tedious years, offering their skills as hard labour which saw the build of the monumental foundations, grand regal structure and battlements. The fact that Flint Castle still dominates this position on the River Dee shows the calibre of skilled labour at the time. Although in ruin, the castle still stands strong to this day and has incredibly withstood the test of time, weather and numerous skirmishes for nearly 1000 years.

Six facts about Flint Castle

  1. Flint Castle was the first of many. The English King, Edward I, demanded that a string of castles were to be built to circle North Wales. These became known as Edward I's 'Iron Ring'.
  2. Not only was Flint Castle used as a battle defence in Medieval times throughout Edward I's reign, it was also used to face horrendous battles during the Civil War years between 1642 - 1651.
  3. Over the years, Flint Castle changed hands numerous times and was even in the possession of the English politician, Sir Roger Mostyn. Mostyn repaired the site after it was weathered by battle and neglect, restoring it in the late 1600's.
  4. Flint Castle's design was inspired by the French fortified towns and strongholds that King Edward I had discovered whilst on his travels, making it the first of its kind in North Wales.
  5. After the Civil War and whilst in the possession of Parliamentarians, Flint Castle was ordered to be demolished. Through the wages of war and ordered dismantlement, Flint's monumental Castle was worn down to nothing but a skeleton of its former glorious past.
  6. Flint Castle and Flint town were built at the same time. Before their significant existence, the land was bare and undesirable to many settlers due to the surrounding high ground and marshy River Dee foreshore.

Many hurdles and complications stunted the progress of Flint Castle’s build, for example, the numerous attacks besieged upon the castle by Welsh royals and their devoted mercenaries. In 1282 Flint’s semi-built fortress and its surrounding grounds were attacked and ransacked by supporters of the Welsh prince, Llywelyn ap Gruffydd, and his brother, Dafydd ap Grufydd. These onslaughts forced the operation to come to a halt for over a month, periodically setting King Edward I and his men at a disadvantage in the ground-breaking battle between the two leaders.


Although the constriction of the castle was completed in 1284, it was destined to be rebuilt and repaired for the remainder of its life. This would be due to continuous attacks and rampages that took place over the following years, including the Welsh surprise strike lead by Madog ap Llywelyn causing the fortified town to burn in a blaze of glory and the revolt of Owain Glyndwr who stormed the grounds on numerous occasions (1400 and 1403) with his loyal army and supporters.
