John Mullowney, who became known as Seán na Sagart, was laid to rest in Ballintubber Abbey graveyard in 1726.
Three centuries later, this commemorative event will revisit his fascinating story and examine the turbulent period of Irish history in which he lived.
Taking place from 3pm until approximately 5pm, the programme will feature a series of talks with strong local connections.
Author Michael O’Connor will provide an overview of the Penal Times during the 1700s and tell the story of Rob Miller from Ballyheane, who served as the official priest hunter for County Mayo.
As Ballintubber Abbey is an Augustinian foundation, the event will also explore the presence and experiences of the Augustinian community in County Mayo during this period.
The afternoon will remember the 24 Irish Catholic Martyrs who were beatified by the Vatican, including St Oliver Plunkett, who was canonised.
The story of Sisters de Burgo and Magaean, martyrs from Newport, will also be explored. Sr Honoria de Burgo is believed to have been a stepsister of Tibbot ne Long, (the son of Granuaile), who is buried at Ballintubber Abbey.
The programme will also examine the Shrule Massacre of February 9, 1642 and its connection to two descendants of Tibbot ne Long: Miles Bourke, 2nd Viscount Mayo, and Theobald Bourke, 3rd Viscount Mayo.
John Hession, a native of Partry and owner of the land on which Seán na Sagart was killed, will present his own account of the priest hunter’s story.
Westport singer-songwriter Charlie Keating will also perform his original composition recounting the life of Seán na Sagart.
Following the talks, attendees will be shown the site in Ballintubber Abbey graveyard where Seán na Sagart is buried. An ash tree now marks the grave.
There will then be an opportunity to travel to Partry to visit Hession’s Field, where the life of John Mullowney came to an end. John Hession will be present to meet visitors and answer questions about the site.
Anyone wishing to take part in this optional visit should wear strong footwear, as the ground is uneven, and allow additional time.
