Bailieborough or Bailieboro (/ˈbeɪlibərə/; Irish: Coill an Chollaigh, meaning 'the wood of the boar')[2] is a town and civil parish in County Cavan, Ireland.

The modern town was founded by William Bailie, a Scottish planter who was granted the lands of Tonergie (Tandragee) in East Breifne by James I, the King of England.

Included in his duties of planting the area, he had to ensure that there were blunderbusses and muskets available so he could arm his men to defend the new plantation.

Originally, a number of thatched houses had developed around the gates of the castle but this was deemed unsightly and it was decided that the settlement would be moved.

Thus, Bailieborough moved to where the current old Church of Ireland chapel is located in the town.

In 1814, the estate was sold to Sir William Young who had returned from travels in the East Indies.

[6][7] A new Catholic church was constructed in 1839, with Phillip O'Reilly as the parish priest at the time.

The Stations of the Cross inside the church were painted by George Collie, an Irish artist in 1956.

[8] On 9 July 1921 the Free State barracks in Bailieboro were attacked and taken, the arms of its garrison being seized.

Their home ground is at St Anne's Park and the club has won five Cavan Senior Football championships.
