Most of Louisburgh lies within the townland of Clooncarrabaun (an anglicisation of Cluain Cearbán). The town was constructed in 1795 by the 3rd Earl of Altamount, (later 1st Marquess of Sligo), John Denis Browne of Westport to house Catholic refugees who fled sectarian conflict in the north of Ireland. Originally a planned town, it retains many of the eighteenth century features in style and scale. The 1st Marquess of Sligo named the town Louisburgh in memory of his Uncle, Captain Henry Browne, who fought on the British side against the French in the 1758 battle of Louisburg. Louisburg (or Louisbourg in French) was a French fortress on Cape Breton Island, Nova Scotia, Canada. As a result of the British victory, a temporary unit of Louisbourg Grenadiers was formed, in which his Uncle was a captain.^[4]

Louisburgh is built on the Bunowen River, part of which is a salmon fishery. Nearby Roonagh Pier, approx 6 km from the town, is the departure point for ferries to Clare Island and Inishturk.

Recently the theatre has received a major boost in the town with the addition of a second drama society.

They then went on to perform the first ever pantomime in Louisburgh helping to raise over 1,000 euro for the local Order of Malta group. Since the group's inception in 2006 they have produced 6 annual pantos Dick Whittington (2006), Cinderella (2007), Aladdin (2008), Snow White (2009), "Robin Hood" (2010) and "Hansel and Gretel" (2011).
