A butter-yellow thatched cottage with rounded bay windows and quatrefoil portholes, sitting like a picture in its own sweep of parkland just outside Bessbrook. Derrymore House is one of the loveliest little houses in the north — and the walk around it is free.
What you'll see — the storybook thatched "cottage orné", a late-18th-century play-house in the fashionable rustic style, set in landscaped parkland with mature trees and long green lawns. From the outside it's a real head-turner.
The Treaty Room — the house's famous room, said to be where the Act of Union was drafted in 1800. A good story, long attached to the place — take it as tradition rather than settled fact.
Room to roam — the estate parkland is open for walks, laid out in the "natural" style with specimen trees and open grass. An easy, pretty stroll rather than a big hike.
How long & who for — an hour or two for a parkland wander and a look at the house from the lawn. Gentle and buggy-friendly on the open grass; lovely for all ages.
The parkland is the day out. The house interior only opens on very limited days, or by arrangement — it is not a turn-up-any-day-and-walk-in visit. Always check with the National Trust before you travel if you want to see inside.
National Trust property. The grounds are free to walk; there's no visitor centre, tea-room or shop on site, so bring your own snacks and use nearby Bessbrook or Newry for food.
Getting there — signed off the road between Bessbrook and Camlough, with a small car park by the estate. Dogs on a lead are welcome around the parkland.
Plan your visit
Free parkland · the house is a very limited visit
The parkland around Derrymore House is open for free walks — no ticket, just an easy loop of lawns and mature trees, with the house itself the star of the view. The house interior is a different matter: as a small, delicate National Trust property it opens only on very limited days, or by prior arrangement, rather than every day. If seeing the inside — and the famous Treaty Room — is your reason for coming, contact the National Trust to confirm dates before you set off. There's no tea-room or shop on site, so plan food around Bessbrook or Newry. Opening details change, so always check the current position before travelling.

Questions
Before you go
Can I just turn up and walk around?
Yes for the parkland — the estate grounds are open for free walks, and the house makes a lovely focal point across the lawn. But the house interior is a separate, very limited visit, so don't count on getting inside without checking first.
Is the house open to go inside?
Only on very limited days, or by prior arrangement — it's a small, delicate National Trust property, not an every-day house tour. Contact the National Trust to confirm dates before you travel if the inside is your main reason for coming.
Is it really where the Act of Union was drafted?
That's the tradition attached to the Treaty Room here — it's said the Act of Union was drafted in the house in 1800. It's a well-known local story rather than a firmly documented fact, so enjoy it as part of the place's history.
How much does it cost?
Walking the parkland is free. If the house interior is open, it's a National Trust property, so members are typically free and non-members may pay — confirm the current arrangement with the Trust, as the house opens only on limited days.
Is there anywhere to eat?
Not on site — there's no tea-room or shop. Bring your own snacks or a picnic, and use nearby Bessbrook or Newry for cafés.
Can I bring the dog?
Yes — dogs on a lead are welcome around the parkland. They're not allowed inside the house.
Getting there
Derrymore House sits just outside Bessbrook, County Armagh, signed off the road toward Camlough, a short drive from Newry. There's a small car park by the estate, and the parkland walk starts right there.
Derrymore House was built in the late 18th century as a country retreat for Isaac Corry, a Newry man who served as a Member of Parliament and, for a time, Chancellor of the Irish Exchequer. Rather than a grand mansion, he chose the fashionable "cottage orné" style — a dressed-up rustic cottage, thatched and painted, designed to look charmingly informal while being anything but simple to build. Its rounded bays, quatrefoil windows and deep thatch make it one of the prettiest houses of its kind anywhere in Ireland. The parkland around it was laid out in the natural, flowing style of the day, and is often credited to the landscape designer John Sutherland.
The house's fame rests on its Treaty Room, where — so the long-held story goes — the Act of Union that joined Ireland and Great Britain was drafted around 1800. How much of that happened in this exact room is a matter of tradition as much as record, but it has fixed Derrymore in the history books all the same. The estate later passed to the National Trust, which cares for the house and its parkland today, keeping the thatch, the yellow walls and the quiet green setting much as visitors would have found them two centuries ago.
