Every day at Howth Castle, a place is set at the dinner table that nobody sits in. It has been this way for nearly five hundred years. The reason comes down to one woman, one locked gate, and a kidnapping that nobody saw coming.
The Pirate Queen Who Would Not Be Ignored
Grace O’Malley — Gráinne Mhaol in Irish — was one of the most powerful figures in 16th-century Ireland. She commanded a fleet of ships from her stronghold on the west coast of County Mayo, trading, fishing, and at times raiding along the Irish coastline and into Scotland.
She was not a woman who accepted being turned away.
In 1576, she was returning by sea from a visit to the English court in London. Her fleet anchored off the north Dublin coast, and she went ashore at Howth Head. She made her way to Howth Castle — the ancestral seat of the St Lawrence family — and presented herself at the gates.
The gates were locked. The family was at dinner and had given orders not to be disturbed.
A Mistake the St Lawrences Would Never Forget
Grace did not leave quietly. On her way back to the harbour, she came across the young heir to Howth Castle — Christopher St Lawrence — walking near the shore. She took him with her.
She sailed west, all the way back to Rockfleet Castle in Clew Bay, County Mayo. The boy was treated well. But she made her terms very clear.
If the St Lawrence family wanted their heir returned, they would agree to two things. First: the gates of Howth Castle would remain open at mealtimes, so that no guest could ever be turned away hungry. Second: a place would always be set at the dinner table for any unexpected visitor.
The family agreed. Christopher came home. And the tradition has been kept ever since.
A Promise Carried Through the Centuries
The St Lawrence family, later the Earls of Howth, reportedly honoured the agreement across generations. Accounts vary on how strictly it was observed at different times, but the story was never forgotten. It passed from parents to children, from family to village, from local legend to written history.
Several accounts from the 18th and 19th centuries mention the open gates and the extra place at table. Lady Gregory, the Irish playwright who helped bring Grace O’Malley’s story to a wider audience, documented the tradition in her writings on Irish folklore.
The St Lawrence family remain connected to Howth Castle and its grounds to this day.

What Howth Castle Is Today
Howth Castle stands above Dublin Bay on the tip of the Howth Peninsula, surrounded by one of Ireland’s most celebrated rhododendron gardens. In early summer, the hillside blazes purple and pink — thousands of visitors make the trip from the city just to walk beneath them.
The castle itself is a private residence, but the grounds and gardens have been open to visitors in recent years. The harbour below is one of the best day trips from Dublin. You can take the DART — Ireland’s coastal rail line — from the city centre in about 30 minutes.
When you get there, the clifftop walking paths offer views across Dublin Bay and out to Ireland’s Eye, the small island sitting just off the headland. The seafood restaurants along the pier are among the best in the Dublin area.
The Explore County Dublin guide covers more of the capital’s best-kept secrets, including places many visitors miss entirely.
The Woman the History Books Nearly Forgot
Grace O’Malley was almost written out of Irish history. For centuries she appeared mainly in local folklore along the Mayo coastline. Official records focused on the men around her. But she commanded fleets, negotiated with Elizabeth I of England as an equal, and sailed until old age.
She was imprisoned twice, outlived two husbands, fought off English colonisation on her own terms, and never stopped being a problem for those who underestimated her.
To understand the full scale of what she did, read the story of the Irish pirate queen who sailed to face the Queen of England and won.
The Open Door
The empty place at the Howth Castle table is one of Ireland’s most quietly remarkable traditions. It started with a locked gate and a woman who refused to accept being turned away.
Five centuries later, it speaks to something that runs very deep in Irish culture: the idea that hospitality is not a favour but a duty. That the door is always open. That there is always room at the table for one more.
