Westport House, the Brownes and the Pirate Queen

A house on a pirate queen's castle

Westport House is one of the finest Georgian houses in Ireland, set on the edge of Clew Bay just outside the town. What gives it its hold on the imagination is what lies underneath. The house stands on the foundations of a castle that belonged to Grace O'Malley, the 16th-century pirate queen of Connacht, known in Irish as Granuaile. Part of that original castle survives in the basement, and it is shown to visitors today as the Dungeons.

Grace O'Malley was a real and formidable figure, a sea captain and clan leader who controlled the waters around Mayo, traded and raided along the coast, and famously sailed to London to negotiate with Queen Elizabeth I. The Browne family who built Westport House are her direct descendants, through the marriage of Colonel John Browne to Maude Burke, one of Grace O'Malley's great-great-granddaughters. The house, in other words, was built by the pirate queen's own family on the pirate queen's own ground.

The Brownes and the building

The Brownes shaped this corner of Mayo for centuries, and they did two great things here. They built the house, and they built the town. The house took form across the 18th century. The German architect Richard Cassels built the east front around 1730, and later architects including James Wyatt and Thomas Ivory worked on it, with the square completed by the 1st Marquess of Sligo in the 1780s. Inside there are original antiques, an art collection and, among the curiosities, an Egyptian sarcophagus.

The same family laid out Westport itself as a planned estate town beside the house, which is why the two stories are really one. The elegance of the town and the grandeur of the house come from the same source, and a visit to one makes more sense alongside the other.

Granuaile in the wider story

If you want to go deeper on Grace O'Malley before or after your visit, the Clew Bay Heritage Centre down on the Quay tells her story well, alongside that of Croagh Patrick and other local figures. She turns up all over this coast, and the version of her you meet at Westport House, ancestor and castle-builder, is only one part of a life that has become genuine legend in the west of Ireland.

Who owns it now

For a long time the house and the title passed together down the Browne line. They separated in 2014 after the death of the 11th Marquess of Sligo, who left the estate to his five daughters. In 2017 the house and its roughly 400-acre estate were bought by the local Hughes family, who own the workwear company Portwest and Hotel Westport. The estate now trades as Westport Estate, and the Hughes family have funded a phased restoration of the house.

Making a visit of it

The house runs guided tours, and the schedule is seasonal, so check the website before you travel rather than turning up on spec. Beyond the house, the estate is a draw in its own right: woodland walks, an 18th-century cascade on the Carrowbeg river, and a celebrated reveal of the house as you approach through the grounds. There is a large outdoor adventure park on the same estate, opened in 2024, though it is booked separately through its own site.

Allow a half day if you want to take in both the house and the grounds at a relaxed pace. Families often spend longer, splitting time between the history indoors and the activities outside. However you do it, the thing to hold onto is the thread that runs through the whole place: a pirate queen, the family she founded, the house they built on her castle, and the planned town they laid out beside it. Few places in Ireland tie their history together so neatly.
