This blog explores the castle’s history, unique architecture, notable figures, and the experiences that make visiting it an unforgettable adventure.

The History of Dolbadarn Castle

Dolbadarn Castle stands as a powerful symbol of Welsh resilience and the ambition of its princes. Built during the 13th century, the castle witnessed key moments in the struggle for Welsh independence and reflects the changing dynamics of power during the medieval period.

The Vision of Llywelyn the Great (Early 13th Century)

Llywelyn ap Iorwerth, known as Llywelyn the Great, constructed Dolbadarn Castle around 1230. He chose the site for its strategic location at the base of Snowdonia, overlooking the Llanberis Pass.

The castle controlled a critical route between Gwynedd and inland Wales. Its position ensured Llywelyn could monitor movements through the valley and protect his territory.

Dolbadarn was more than just a military outpost. It served as a statement of Llywelyn’s authority, showcasing his ability to build castles comparable to those of his Norman adversaries. The round tower, a hallmark of native Welsh architecture, emphasized this point.

Additionally, Dolbadarn symbolized Llywelyn’s vision for a unified and independent Wales. It was one of several castles he constructed to consolidate his power and protect his borders.

The Role of Dolbadarn in Welsh Resistance

During the mid-13th century, Dolbadarn Castle continued to play a vital role in Gwynedd’s defenses. It became a base for Llywelyn’s successors as they navigated alliances and conflicts with the English Crown.

Llywelyn ap Gruffudd, also known as Llywelyn the Last, inherited the castle. He used it as a strategic stronghold during his campaigns to maintain Welsh independence.

In the late 1270s, Llywelyn the Last imprisoned his brother, Owain Goch, in the round tower of Dolbadarn. This act reflected the internal power struggles within Gwynedd, as Llywelyn sought to secure his rule against potential rivals.

However, Dolbadarn’s significance diminished after Llywelyn’s death in 1282 at the hands of Edward I’s forces. Edward’s victory marked the end of independent Welsh rule, and Gwynedd fell under English control.

Edward I and Dolbadarn’s Decline

After conquering Wales, Edward I captured Dolbadarn Castle in 1284. Although he recognized its strategic value, Edward focused on building his own castles, such as Caernarfon, Harlech, and Conwy.

The stone from Dolbadarn was repurposed for these larger and more elaborate fortifications. As a result, Dolbadarn’s role shifted from a key stronghold to a lesser outpost.

By the 14th century, the castle had fallen into disrepair. Its military importance faded, and its remaining structures became part of the rugged landscape of Snowdonia.

Romantic Rediscovery in the 18th and 19th Centuries

Dolbadarn Castle gained renewed attention during the Romantic era of the 18th and 19th centuries. Poets, painters, and writers admired its dramatic ruins and the beauty of its surroundings.

The castle inspired artists like J.M.W. Turner, whose paintings of Dolbadarn emphasized its historical and aesthetic appeal. Romantic depictions of the castle played a significant role in preserving its legacy and attracting visitors to Llanberis.

Preservation and Modern Significance (20th Century–Present)

In the 20th century, efforts to preserve Dolbadarn Castle began as interest in Welsh heritage grew. The site is now managed by Cadw, the Welsh government’s historic environment service.

Today, Dolbadarn Castle is celebrated as a symbol of Welsh independence and identity. Visitors from around the world come to explore its ruins and learn about its role in medieval history.

The Architecture of Dolbadarn Castle

Dolbadarn Castle is a quintessential example of native Welsh military architecture. Built during the early 13th century by Llywelyn the Great, its design reflects both practicality and symbolism. The castle’s architecture serves as a statement of Llywelyn’s power, showcasing his ability to rival the Norman and English fortifications of the time.

The Round Tower: A Masterpiece of Welsh Design

The most iconic feature of Dolbadarn Castle is its round tower, which dominates the site. Standing over 50 feet tall and approximately 40 feet in diameter, the tower exemplifies both strength and sophistication.

Construction: The tower is built from locally quarried slate and stone, blending seamlessly with the surrounding landscape. Its thick walls, some reaching up to 8 feet, provided immense durability and defense against siege attacks.
Functionality: The tower served as both a defensive keep and a residence. Its height allowed for excellent views of the Llanberis Pass, making it ideal for monitoring enemy movements.
Interior Layout: The tower consists of multiple levels connected by a spiral staircase. The ground floor likely functioned as a storage area, while the upper levels housed living quarters. The presence of fireplaces and latrines highlights its dual purpose as a fortress and a royal residence.

Curtain Wall and Bailey

Dolbadarn Castle was originally surrounded by a curtain wall, which enclosed a courtyard or bailey. Though much of this wall has eroded, remnants remain, offering insight into the castle’s overall layout.

Curtain Wall: The stone curtain wall protected the interior buildings from direct attacks. Arrow slits and battlements allowed defenders to fire on advancing enemies while remaining shielded.
Bailey: The bailey housed essential structures such as barracks, storage areas, and a hall for gatherings. The layout suggests that Dolbadarn was not only a military stronghold but also a functioning administrative center.

Strategic Location and Natural Defenses

Dolbadarn Castle’s site was chosen for its natural defensive advantages. It occupies a steep hill near the Llanberis Pass, a critical route through Snowdonia.

Elevation: The castle’s elevated position made it difficult for attackers to approach without being seen or exposed to defensive fire.
Surrounding Terrain: The rocky hills and nearby lakes, Llyn Padarn and Llyn Peris, created natural barriers, further enhancing the castle’s security.

This strategic placement reflects Llywelyn the Great’s understanding of the landscape and his ability to use it to his advantage.

Architectural Symbolism

Dolbadarn Castle’s architecture reflects the ambition and identity of Llywelyn the Great. Unlike Norman castles, which often prioritized military functionality, Dolbadarn also emphasized its symbolic role.

The Round Tower’s Significance: The tower’s design was inspired by contemporary Norman and English castles but adapted to reflect native Welsh styles. Its imposing height and robust structure were meant to convey Llywelyn’s authority and legitimacy as a ruler.
Integration with Nature: The use of local materials and the castle’s harmony with the surrounding landscape underscore its connection to Welsh identity.

Architectural Innovations

Dolbadarn Castle incorporated advanced design elements for its time, blending Norman influences with traditional Welsh techniques.

Spiral Staircase: The tower’s internal spiral staircase allowed for efficient movement between levels while making it difficult for attackers to ascend.
Defensive Features: The combination of thick walls, narrow arrow slits, and the elevated site made the castle nearly impregnable.
Water Access: Proximity to Llyn Padarn ensured a steady water supply, critical during prolonged sieges.

Modern Impressions

Though much of Dolbadarn Castle lies in ruins, its round tower remains remarkably intact. This feature, along with the surviving sections of the curtain wall, continues to inspire admiration for Llywelyn’s vision and the ingenuity of medieval Welsh builders.

Visitors exploring the site today can see the craftsmanship that went into its construction, from the precisely fitted stonework to the enduring stability of the tower.
