Celtic Symbols and Their Meanings
Celtic jewellery is full of symbols, and many of them are younger than people think. This guide gives the meaning of each one in plain words. It also says where the evidence is firm, and where a meaning comes from modern times.
Knowing the story makes a piece more special, because you can pass it on to the person who wears it. For a ring, read our Claddagh ring guide as well.
Celtic knot
A Celtic knot is a pattern of lines that cross over and under with no start or end. Artists in Ireland and Britain used it widely from the 7th century, in books such as the Book of Kells and on carved stone. The idea of weaving came from the late Roman world, where floor mosaics from the 3rd and 4th centuries show similar knots. Today most people read the endless line as a sign of eternity.
Trinity knot (triquetra)
The trinity knot is a three-pointed shape made from one unbroken line. It appears in Irish and British art from about the 7th century. Many people link it to the Christian Trinity, although that reading became popular mainly in the 19th century. Others use it for past, present and future, or for body, mind and spirit. Nobody knows what the first artists meant by it.
Claddagh
The Claddagh shows two hands holding a crowned heart, for friendship, love and loyalty. Galway jewellers have made it since at least 1700. It is Irish and fairly young, so it is not an ancient Celtic symbol. Our Claddagh guide tells the full story.
Tree of life
The tree of life is an idea found in many cultures. It shows a tree whose roots, trunk and branches join the ground, the earth and the sky. Modern Celtic jewellery borrows the idea and often weaves knotwork into the branches. The design stands for growth, family and a fresh start.
Celtic cross (high cross)
A Celtic cross is a cross with a ring around the crossing. Craftsmen carved stone versions, called high crosses, in Ireland and Britain from about the 8th to the 12th century. Famous ones stand at Ahenny, Monasterboice, Moone and Kells. Early crosses show knotwork, and later ones show scenes from the Bible. Historians are not sure why the ring appeared, although it may first have strengthened the stone.
Spiral
Spirals are among the oldest marks in Ireland. The passage tomb at Newgrange, built more than 5,000 years ago, carries spirals and a triple spiral. Its builders lived long before the Celts, so we should call these designs ancient rather than Celtic. Celtic artists did use spirals later, and jewellers still do.
Ogham
Ogham is an early Irish alphabet. People carved it along the edge of standing stones from about the 4th century AD. Each letter is a set of short strokes cut across a central line. Most stones record a name. Jewellers use it to spell a word such as "love" or "faith". The popular link between each letter and a tree is a later idea.
Shamrock
The shamrock is a three-leaved clover and a symbol of Ireland. The tale that St Patrick used it to explain the Trinity is told in print from the 1700s, long after his time. Since the 18th century the shamrock has stood for Ireland itself, and it is a lucky charm for many people.
Torc
A torc is a stiff neck ring, open at the front. Iron Age people across Europe wore gold, bronze and silver torcs, and the Celts wore them as a mark of high rank. Modern torc bangles copy the open ring shape on the wrist.
Celtic symbol questions
What is the most popular Celtic symbol?
The Celtic knot and the trinity knot are the designs most often seen on jewellery. The Claddagh is the favourite for rings. Because each design has its own meaning, many buyers choose by the message.
What does the trinity knot represent?
Most people link it to the Christian Trinity, or to past, present and future. Historians note that the Trinity reading grew common in the 19th century. The original meaning is unknown.
Are Celtic symbols religious?
Some are, and some are not. The high cross is Christian, and Ogham is an alphabet. People used knots and spirals in both settings, so people of any belief can wear them.
What is the oldest Celtic symbol?
Spirals are far older than the Celts, as the carvings at Newgrange show. Among truly Celtic styles, the early curves and spirals of Iron Age metalwork come first. Knotwork came later, from about the 7th century.
