The Story of the Killybegs Name

The Irish name Na Cealla Beaga means “the little churches.” Cill means “church,” cealla is its plural form, and beaga means “little.” The name points to the early Christian foundations that once stood in the area.

Killybegs lies on the south coast of Donegal, overlooking Donegal Bay. Its exceptionally deep natural harbour has made it one of Ireland's most important fishing ports and has shaped the town's history for centuries.

The religious history behind the name is traditionally associated with St. Catherine, whose church and holy well are connected with the area. The surviving St. Catherine's Well near the harbour remains a place of local devotion.

During the medieval period, Killybegs was part of the Gaelic world of Tír Chonaill, dominated by the powerful O'Donnell dynasty. Its harbour provided access to the Atlantic and gave the region an important connection with maritime trade.

The town's fortunes changed dramatically in the seventeenth century. Following the Flight of the Earls, Gaelic political power collapsed, and the O'Donnell lands were confiscated. Killybegs subsequently came under English control.

Its harbour, however, remained valuable.

During the seventeenth and eighteenth centuries, Killybegs became an important port for trade and fishing. The sheltered waters provided a safe anchorage for vessels, while the rich fishing grounds off the Donegal coast supported a growing maritime economy.

The nineteenth century brought further development, particularly with improvements to the harbour. Killybegs became increasingly important as a fishing center, and the surrounding community became closely connected with the sea.

The town's fishing industry expanded dramatically during the twentieth century. Modern trawlers transformed Killybegs into one of the largest fishing ports on the island of Ireland.

The harbour has also had an important role beyond fishing. It has served commercial shipping and provided shelter for vessels crossing the Atlantic, continuing a maritime tradition that reaches back centuries.

Yet the name itself takes us much further back:

Na Cealla Beaga — the little churches.

Before the great fishing boats, before the harbour works, before modern industry, there were small Christian churches scattered across this coastal landscape.

The name preserves their memory.

That makes Killybegs a particularly lovely example of the layers contained within an Irish place-name: faith first, then Gaelic lordship, then maritime trade and finally the great fishing industry of modern Donegal.

Killybegs is a place where the sea has always been central—but its name reminds us that long before it became famous as a fishing port, it was known for something much smaller: little churches.
