Historic Sites in County Armagh

Half of these ten sites sit within a short drive of Armagh city. Navan Fort is the oldest by a long way: a 40-metre mound raised over a vast timber roundhouse that was packed with stone, burnt and buried around 95 BC, known in Irish as Eamhain Mhacha. Entry to the site and its centre is free. In the city, St Patrick’s RC Cathedral took from 1840 to 1904 to finish, the Famine having stopped work outright, and the mosaic sanctuary is the reason to go inside. The courthouse and gaol face each other along the Mall, but neither opens for ordinary interior visits.

North of the city the list turns to country houses. The Argory, outside Moy, still holds the acetylene gas fixtures that lit it from 1906 into the early 1980s, with gardens and Blackwater riverside walks around it. Ardress House sets Michael Stapleton plasterwork against a cobbled farmyard and a half-hour woodland loop, which makes it the easier one with children. Brownlow House, on the edge of Lurgan, counts out the year in wings, corners and chimneys; its museum is by appointment, so ring before you set off.

South Armagh needs a car. Ballykeel Dolmen sits on the western flank of Slieve Gullion, and reaching the Kilnasaggart pillar, inscribed in Old Irish and datable to around 714, means a lay-by and two or three fields on foot.

Navan Fort – Ulster's mythic capital

Armagh, armagh

The 40-metre mound here was built as a vast timber roundhouse, deliberately filled with stone, burnt and covered in earth around 95 BC. Known in Irish as Eamhain Mhacha, it was the mythic seat of Conchobar mac Nessa and the Red Branch Knights, and surveys since 2020 have found far larger temple structures across the hilltop. Entry to the site and centre is free.

Questions people ask

Which historic sites in County Armagh can I visit for free?
Navan Fort charges nothing for either the site or its visitor centre, and the military exhibitions at Brownlow House in Lurgan are free, though the museum there works by appointment only. Charges for the National Trust properties are worth checking before you travel.
Which ones are walkable from Armagh city centre?
St Patrick's RC Cathedral, the courthouse and gaol at either end of the Mall, and Milford House on Victoria Street are all in the city itself. Navan Fort lies a short drive out. The country houses and the south Armagh monuments all need a car.
Which of these can you actually get inside?
The cathedral, The Argory, Ardress House and Milford House all open their interiors, and Brownlow House does by appointment. The courthouse is a working court and the gaol has no regular interior access, though the gaol runs occasional heritage tours and has a 360 degree virtual walkthrough online.
How hard is it to reach Ballykeel Dolmen and the Kilnasaggart stone?
Both sit in south Armagh and need a car. Ballykeel Dolmen is on the western flank of Slieve Gullion at the south end of a long cairn. Kilnasaggart, near the Moyry Pass, means parking in a lay-by and crossing two or three fields, so wear boots.
Which are the best bets with children?
Ardress House has a cobbled farmyard with animals and the Lady's Mile woodland walk, which loops round in about half an hour. Ballymoyer near Whitecross follows the Creggan River through a mossy glen, and Navan Fort gives an open hilltop to run about on.
