Caerdroia

Lore & Background

The caerdroia is a Welsh turf maze, usually in the sevenfold Cretan labyrinth design. They were created by shepherds on hilltops and were apparently the setting for ritual dances, the nature of which has been lost. At the centre of each caerdroia was a small hillock—in Welsh, twmpath. A gathering for folk dancing in Wales is still called a twmpath dawns. While the caerdroia is typically Welsh, similar turf mazes have been found elsewhere in Britain and Europe, though no verified examples outside Wales are widely accepted in established sources.

The etymology of the word caerdroia includes meanings such as 'a labyrinth, a maze; maze cut by shepherds in the sward, serving as a puzzle' and also 'Troy, Walls-of-Troy'. Because of the similarity between Welsh troeau (a plural form of tro 'turn') and the second element Troea ('Troy'), the name was later popularly interpreted as meaning 'fortress of turns' (caer = 'fort').

Reader's Guide

The caerdroia represents a distinctive Welsh tradition of turf mazes, typically in the sevenfold Cretan labyrinth design, created by shepherds on hilltops. Their significance lies in their ritual use for dances, the nature of which has been lost, and their connection to folk gatherings still called twmpath dawns. The etymology linking the word to 'Troy' reflects a broader European tradition of naming mazes after the legendary city, whose walls were said to be confusingly constructed. The discovery of a caerdroia in Petrella Tifernina, Italy, by historian Mario Ziccardi shows that the tradition extended beyond Wales. The modern example in Gwydir Forest, built in 2005, demonstrates the enduring appeal of these labyrinths, with paths measuring a mile in length, possibly the largest of its kind. The caerdroia also connects to the legendary founding of Britain by Brutus of Troy, as recorded by Geoffrey of Monmouth and Nennius, a genealogy that retains wide belief despite dismissal by some historians. Overall, the caerdroia is a cultural artifact blending landscape, ritual, and myth.

Did You Know?

• At least one caerdroia is known to have been constructed abroad, discovered by historian Mario Ziccardi in Petrella Tifernina, Italy.
• The Caerdroia in Gwydir Forest, built in 2005, has paths measuring a mile in length, making it possibly the largest labyrinth of its kind in the world.

Shepherd's Craft and the Lost Ritual

A caerdroia is a turf-cut maze traditionally found in Wales, most often following the sevenfold Cretan labyrinth pattern. These structures were carved by shepherds into the grass on hilltops, serving as a kind of puzzle or challenge. What makes them particularly fascinating is their connection to ritual: they were apparently the setting for ceremonial dances, though the precise nature of those dances has been lost to history. At the heart of every caerdroia stood a small mound of earth called a twmpath. This word lives on in modern Welsh culture, where a twmpath dawns still refers to a gathering for folk dancing. The shepherds who created these mazes were not merely passing the time; they were building spaces for communal celebration and spiritual practice, embedding their craft into the living landscape of the Welsh hills.

The Name, the Turns, and the Walls of Troy

The name caerdroia carries layers of meaning that reveal how deeply the Welsh connected their mazes to classical mythology. In Welsh, the word literally translates to a labyrinth or maze cut by shepherds in the sward, serving as a puzzle. Yet it simultaneously means Troy or the Walls of Troy. Because the second element, Troea, resembles troeau (the plural of tro, meaning turn), later popular interpretation recast the name as fortress of turns, with caer meaning fort. This Troy association was not confined to Wales. Across England, numerous turf mazes were given names like Troy Town or The Walls of Troy, drawing on the popular legend that the walls of the ancient city were built so confusingly that no invading enemy could ever find his way out. The connection deepens further through Geoffrey of Monmouth, who, following the earlier Welsh historian Nennius, composed a genealogy placing Brutus of Troy—grandson of Aeneas and liberator of enslaved Trojans—as the founder of Britain. Though some historians dismiss this lineage, it retains wide popular belief and cements the mythological bond between Welsh mazes and the legendary city.

Gwydir Forest: A Labyrinth Grown Into the Woodland

One of the most striking modern examples of the caerdroia tradition stands in Gwydir Forest, high above the Conwy Valley in Wales. Constructed in 2005 at Pen-y-Parc—one of the forest's highest points—this permanent labyrinth was built collaboratively by Theatre Cynefin, Golygfa Gwydyr (a social enterprise based in Llanrwst), and local young people. Its paths stretch a full mile in total length, making it possibly the largest labyrinth of its kind anywhere in the world. The site has become a living performance space: initially hosting shows by Theatr Cynefin, and from 2012 onward by Theatr Dan-y-Coed. What began as a grassy clearing has transformed over the years as the low conifers planted between the paths have grown substantially, weaving the maze into the surrounding woodland. The caerdroia is no longer simply a structure placed in the forest; it has become an organic, integral part of the Gwydir landscape itself.

A Global Puzzle: Italian Discoveries and International Scholarship

Although the caerdroia is fundamentally a Welsh tradition, its reach extends further than one might expect. Historian Mario Ziccardi identified at least one example constructed abroad, discovered in Petrella Tifernina, Italy, a finding he published in 2015 in the journal Caerdroia: The Journal of Mazes and Labyrinths. The broader scholarly conversation around mazes and labyrinths is rich and international. Adrian Fisher and Georg Gerster explored the artistic dimensions in The Art of the Maze (1990), while Jeff Saward devoted his book Magical Paths (2002) to the spiritual and symbolic significance of these pathways. Janet and Colin Bord included mazes in their survey of Mysterious Britain (1974), and Kermann Kern offered a sweeping five-thousand-year history of the labyrinth as a universal archetype in his German-language work Labyrinthe (1981). Organizations like the Labyrinth Society and the Labyrinthos website continue to catalogue and celebrate these structures worldwide, ensuring that the ancient shepherd's puzzle remains a subject of active study and wonder.
