Delvin Castle and Clonyn Castle
Delvin Castle (or Nugent Castle), now a ruin, was built in 1181 by Hugh de Lacy, Lord of Meath for his brother-in-law, Gilbert de Nugent. De Nugent came to Ireland with de Lacy in 1171 and settled on some land in Delvin. De Nugent was granted the title Baron of Delvin within the Lordship of Meath, a title now held by the Earl of Westmeath. The ruins of Nugent Castle (not publicly accessible) remain near the center of the town.A second castle was built several centuries later, hundreds of metres from the centre of the Delvin settlement of that time. This building, known as Clonyn Castle, is situated south of Delvin between the N52 and the Collinstown road. Built in the mid-19th century, by Lord and Lady Greville Nugent, it was sold by the Nugent family in 1922. Changing hands several times during the 20th century, it is now a private residence.
The 18-hole Delvin Castle Golf Club is located near the town. There is a bank, church, hotel/guest house, schools, pubs, a few shops and a take-away in the town. There are also a few pubs on the main street.
Between the 2002 and 2016 census, the population of the town more than doubled from 270 to 740 people. In addition to other developments, plans were unveiled for the provision of a new sports and leisure facility within the village.
