The Irish Famine of 1740–1741 in the Kingdom of Ireland, is estimated to have killed between 13% and 20% of the 1740 population of 2.4 million people, which was a proportionately greater loss than during the Great Famine of 1845–1852.

The Conolly Folly, a.k.a. The Obelisk, is an obelisk structure located between Celbridge, Leixlip and Maynooth in County Kildare, Ireland. It was built in the mid-18th century by the Conolly family, then owners of the Castletown Estate. It was restored in the mid-20th century by the Irish Georgian Society, and is now a national monument in state care.
