Omagh

The county town of Tyrone, where the Drumragh and Camowen meet to form the Strule. In August 1998, months after the Good Friday Agreement, a car bomb killed 29 people and unborn twins — the single deadliest attack of the Troubles, and one that hardened the peace rather than breaking it.

Omagh is An Ómaigh, the virgin plain. A monastery seems to have been founded here around 792 and a Franciscan friary in 1464; the town itself was founded in 1610. It sheltered refugees from east Tyrone in 1641, and in 1689 James II passed through on his way to Derry; Williamite supporters later burned the town. In 1768 it replaced Dungannon as county town. The railways came in the 1850s and 1860s, and were all closed by 1965, leaving Tyrone with no railway. On 15 August 1998 a Real IRA car bomb killed 29 people in the town centre and injured hundreds.

• Knockmany — Fionn and Oonagh’s hill · Folklore gives this hilltop to Fionn mac Cumhaill and his wife Oonagh. Older by far is what is actually on it: a passage tomb of about 3000 BC, thirteen sandstone uprights carved with spirals, circles and zigzags. The name is Cnoc mBáine — Báine’s hill, for a goddess of whiteness later folded into Áine.
