The medieval name
Loughsewdy
Before it was Ballymore it was Loughsewdy — the borough by Lough Sewdy. The De Lacy family founded a monastery here in 1218 for Premonstratensian canons and Benedictine nuns, which is an unusual mixed arrangement and not one that lasted. The lake's name in the Annals of the Four Masters is Loch Seimhdidhe. On the Down Survey it appears as Lough Sunderlin. The village kept moving on; the old names didn't.
Henry VIII's short experiment
The cathedral that nearly was
In the 1540s Henry VIII briefly moved the seat of the Diocese of Meath to the abbey at Ballymore. It didn't last. The episcopal seat went elsewhere within a few years and the abbey slid into ruin. The current St Owen's Church on the site was built in 1827 with a Board of First Fruits loan, closed in 1959, and lost its roof in 1964. The graveyard around it has stones older than the church it shadows.
A village half-empty in the 1860s
The road to Argentina
From the end of the Famine into the 1880s, Ballymore and the townlands around it sent more people to Argentina than to America. They were non-inheriting middle children of Catholic farming families, drawn by cheap land on the pampas and a Westmeath priest in Buenos Aires telling them to come. A 2026 RTÉ piece called the village the epicentre of midlands emigration to South America. Most homes here still have a cousin or three on the other end of that line.
Uisneach in May
The Bealtaine fire
The Hill of Uisneach, eight kilometres east of the village along the R390, is the mythological centre of Ireland and the site of the great Bealtaine fire. The festival on the hill draws thousands to the first weekend in May. The village fills up for two nights and empties again. The rest of the year the hill is a quiet walk on private farmland with guided tours by appointment.
