Glasgow traces itself to a single act of faith. By tradition, some time around the middle of the sixth century a monk built a small church on a green rise above a stream called the Molendinar Burn, and around it a settlement gathered that would one day become a great city. The monk was Kentigern, whom those who loved him called Mungo. Almost everything we know of him comes from legend, set down in writing some six hundred years after his death — but Glasgow has carried his memory, and four of his miracles, on its coat of arms ever since.
This page tells his story as tradition records it: the strange tale of his birth, the founding of his church, the four famous miracles, and the city and cathedral that grew from his grave.
Kentigern & Mungo
The saint was properly called Kentigern, a name from the old Brittonic tongue once spoken across southern Scotland. But he is remembered above all by his pet-name, Mungo, said to mean something like ‘dear one’ or ‘dear friend’ — a name that has stuck to him, and to the city he founded, for fifteen centuries. The stories of his life were written down only around 1180, by a monk named Jocelyn of Furness, so they are less sober biography than pious legend; yet they preserve the memory of a real missionary who brought Christianity to the Clyde valley.
A miraculous birth
Legend gives Mungo a dramatic and tragic beginning. His mother was Teneu, a British princess whose furious father is said to have cast her from the heights of Traprain Law when she fell pregnant. She survived the fall, and was set adrift alone in a small boat, which carried her across the Firth of Forth to Culross in Fife. There the child was born, and there both mother and son were taken in by the holy man Saint Serf. Teneu herself came to be venerated as a saint — Glasgow’s other patron, remembered in the city’s St Enoch, a worn-down form of her name.
The church by the Molendinar
Raised and taught by Saint Serf, Mungo grew to be a missionary, and in time made his way west to the little community on the banks of the Molendinar Burn. There, the story goes, he found the grave of a holy man named Fergus, and beside it built his church, around the year 543. The place was called Glasgu — often translated as the ‘dear green place’, though the true meaning is debated. From that modest beginning grew both a bishopric and a town, and Mungo is honoured as the founder of them both.
Bishop, exile & return
Mungo became bishop of the new Christian community on the Clyde, and gathered disciples about him. But these were dangerous times, and tradition tells that a hostile king drove him into exile for a season. He is said to have travelled far south, to Cumbria and to Wales, founding churches as he went — the Welsh see of St Asaph claims him among its founders — before a change of fortune allowed him to return to his beloved Glasgow, where he took up his ministry once more and lived to a great age.
The four miracles
Four wonders attributed to Mungo are woven into the very identity of Glasgow, for they are remembered on the city’s coat of arms: a bird, a tree, a bell and a fish. The bird was a robin, killed by others but restored to life by the young saint; the tree recalls a fire he miraculously rekindled from a frozen branch when the flames had died; and the bell was one he is said to have brought back from Rome. The most famous miracle of all, though, is the fourth — the fish and the ring.
Death & the shrine
The tale tells of a queen of Strathclyde who had given away a royal ring, and whose husband, discovering it gone, threatened her with death unless she produced it. In her desperation she turned to Mungo, who sent a monk to fish in the Clyde; the first salmon caught had the missing ring in its mouth. It is from this story that the fish with a ring appears in Glasgow’s arms. Mungo himself died, by tradition, on 13 January in the year 614, and was buried at the church he had founded — the spot where Glasgow Cathedral stands today.
Mungo’s Glasgow
From the saint’s grave grew one of the greatest churches in Scotland, and around his shrine medieval Glasgow flourished as a place of pilgrimage — the cathedral rising over his tomb, which still lies in its lower church. His name and his miracles endure everywhere in the city: in the coat of arms, in the motto ‘Let Glasgow Flourish’ drawn from words attributed to him, in place-names and dedications across the town. Fifteen hundred years on, the dear green place still belongs, in memory at least, to its dear friend Mungo.

A note on dates: the year 543 and the miracle stories come from a life of Saint Kentigern written around six centuries after the events it describes. They are recorded here as the city's founding tradition, distinct from documented history, which begins to firm up with the cathedral and bishopric of the twelfth century.
Frequently asked questions
Who was Saint Mungo?
Saint Mungo, also called Kentigern, was a sixth-century missionary honoured as the founder and patron saint of Glasgow. By tradition he built his church where Glasgow Cathedral now stands, and the settlement that grew around it became the city.
Why is he called Mungo as well as Kentigern?
Kentigern was his formal name, from the old Brittonic language of southern Scotland. ‘Mungo’ was an affectionate nickname, thought to mean ‘dear one’ or ‘dear friend’, and it is the name by which Glasgow has always best known him.
How did Saint Mungo found Glasgow?
According to tradition, around the year 543 he built a small church beside the Molendinar Burn, at the grave of a holy man called Fergus. A community gathered around it, and from that church grew both the bishopric and the city of Glasgow.
What are the four miracles of Saint Mungo?
They are the bird he restored to life, the fire he rekindled from a frozen branch, the bell he brought from Rome, and the fish that carried a lost ring in its mouth. All four appear on the coat of arms of the City of Glasgow.
What is the story of the fish and the ring?
A queen of Strathclyde had given away a ring, and her husband threatened her with death unless she returned it. She appealed to Mungo, who had a salmon caught in the Clyde — and the ring was found in its mouth. It is the source of the fish-and-ring emblem in Glasgow’s arms.
When is Saint Mungo’s day?
Saint Mungo’s feast day is 13 January, the traditional date of his death in the year 614. It is still marked in Glasgow, the city he is said to have founded.
Where is Saint Mungo buried?
By tradition he was buried at the church he founded, on the site where Glasgow Cathedral now stands. His tomb lies in the cathedral’s lower church, and the great medieval building rose up around his shrine.
