Tullyhogue Fort (also spelt Tullaghoge or Tullahoge) sits on a gentle rise just outside the village of Tullyhogue, a few kilometres south‑south‑east of Cookstown in County Tyrone. The site is a large, polygonal earthwork surrounded by mature trees, offering sweeping views across the rolling Ulster countryside and, on a clear day, the distant Slemish Mountains. Managed as a State Care Historic Monument, the fort is open all year, free of charge, and provides a rare glimpse into the ceremonial heart of medieval Ulster.

History

The origins of Tullyhogue Fort are shrouded in pre‑historic mystery; archaeologists have uncovered Mesolithic flint fragments dating to before 5000 BC, indicating that the hill has been a focal point for human activity for millennia. By the 11th century the site had become the dynastic centre of the Cenél nEógain, later the powerful O’Neill clan. It served as the inauguration ground where the title An Ó Néill (‘The O’Neill’) was bestowed on each new chief.

The inauguration ritual was a spectacular affair. The head of the O’Hagan clan, hereditary guardians of the hill, acted as the chief inaugurator, while the head of the O’Cahan clan, the principal sub‑chief, would fling a golden sandal over the new lord’s head – a symbolic gesture of good fortune. The sandal was then placed on the chief’s foot and a rod of office presented. The central stone of the ceremony, the Leac na Rí (‘flagstone of the kings’), was later incorporated into a stone chair surrounded by three large slabs. This stone was famously illustrated by Tudor cartographer Richard Bartlett in the early 17th century.

The last Gaelic inauguration took place in the 1590s – IrishCentral records the year as 1593, while Wikipedia cites 1595 for Hugh O’Neill, Earl of Tyrone. In 1602, during the Nine Years’ War, English commander Lord Mountjoy smashed the Leac na Rí to symbolically end O’Neill sovereignty, an act that marked the end of the native Gaelic order in Ulster.

Recent archaeological work (2014) by the Centre for Archaeological Fieldwork at Queen’s University uncovered further Mesolithic artefacts, underscoring the site’s long‑term significance. A £500,000 investment has since upgraded visitor facilities, added interpretive signage, and improved access routes.

What to See & Do

  • The Earthworks – Walk the low, embanked enclosure and imagine the ancient crowd gathered for a king’s coronation. The layout – a raised mound, an outer bank and a wide flat space – was designed for visibility and ceremony rather than defence.
  • Panoramic Views – From the summit you can see for miles across County Tyrone. The Slemish Mountains dominate the horizon, and the surrounding fields and hedgerows create a quintessentially Ulster tableau.
  • Picnic Area – A newly created picnic spot near the base of the hill offers a pleasant place to rest after the 45‑minute ascent. Benches and tables are provided, and the site is popular with families.
  • Interpretive Panels – On‑site information boards detail the inauguration rites, the role of the O’Hagan and O’Cahan families, and the fate of the Leac na Rí.
  • Walking Routes – The path to the fort is a well‑maintained tarmac track, suitable for children and wheelchair users where the gradient permits. The walk is a gentle step‑incline taking roughly 45 minutes round‑trip, with optional extensions that loop through nearby farmland and woodland.

Getting There

The fort lies in the townland of Ballymully Glebe, about 2½ miles (4 km) south‑south‑east of Cookstown. From the B162 Cookstown‑Stewartstown road, turn onto Tullywiggan Road and follow the signs to the car park at the foot of the hill. The drive is well‑signposted and takes roughly 10 minutes from Cookstown town centre. Public transport options are limited; most visitors arrive by car.

Visiting Tips (Integrated into the Narrative)

When you arrive, park in the designated lot and follow the short, clearly marked trail up the hill. The ascent is steady but not strenuous; the tarmac surface makes it comfortable for families and older visitors. Once at the top, take a moment to absorb the historic atmosphere – the earthworks, the stone chair reconstruction, and the sweeping vista all combine to evoke the power once exercised here.
