The Story of the Markethill Name

The name Markethill comes from the Irish Cnoc an Mhargaidh, meaning “Hill of the Market.” It is an unusually transparent place-name: cnoc means “hill,” while margadh means “market.” The Irish form is essentially a Gaelic rendering of the English name. Historical sources record the place as Market Hill, and the Irish form Cnoc an Mhargaidh is a direct translation.

The town grew during the Plantation of Ulster, when Sir Archibald Acheson, a Scottish settler, received land in the area in the early seventeenth century. Acheson established his estate around what was then the townland of Coolmallish, and a settlement gradually developed along the important road between Armagh and Newry.

The market was at the heart of the town's development. Markethill became a place where farmers from the surrounding countryside could bring livestock and agricultural produce to sell, turning the settlement into an important local trading center. That tradition has survived remarkably well: Markethill remains associated with its livestock market today.

But perhaps the most fascinating chapter in Markethill's story involves Gosford Castle. The Acheson family rose in status over the generations, eventually becoming the Earls of Gosford. In the early nineteenth century, the 2nd Earl of Gosford commissioned architect Thomas Hopper to create an enormous Norman Revival castle on the estate. Construction began in 1819, producing one of the great romantic castle buildings of nineteenth-century Ireland.

Markethill also has a literary connection that is easy to overlook. Jonathan Swift, author of Gulliver's Travels and Dean of St Patrick's Cathedral in Dublin, stayed with the Acheson family at Markethill during three summers in the late 1720s and early 1730s. His time there inspired several poems, including “The Grand Question Debated,” which humorously considered what should be done with nearby Hamilton's Bawn.

The surrounding Gosford estate eventually became Gosford Forest Park, bringing another layer to the town's story. Today, visitors can walk among the estate's ancient woodland and see the extraordinary castle that once belonged to the family responsible for much of Markethill's development.

So while the name sounds almost wonderfully ordinary, Markethill preserves the reason for its existence right in its name: a market established on a hill, around which a community grew.

Markethill is a reminder that sometimes an Irish place-name doesn't require a complicated translation. The name tells the story plainly: a hill, a market, and a town that grew around them.
