The Holy Well and Graveyard dedicated to St. Movee are very ancient - the well itself may be 4,500 years old. There would have been a monastic settlement here in the 8th and 9th. century. Milverton's history is closely associated with the Priory of St. Patrick at Holmpatrick until its dissolution in 1537. The monastic estate, including Milverton, became the property of King Henry VIII, and was sold on to Mr. John Parker. The next ownership record we have is that of Sir Thomas Fitzwilliam of Baggotrath and Merrion, and next Mr. James Fullerton, who in 1608 sold it to Donough O' Brien the Earl of Thomond. The land was leased then to a captain Nicholas Coddington and was held by him at the time of the1659 census. It remained in the Coddington family until 1721 when the Earl of Thomond sold the estate to Hans Hamilton.

This estate has been maintained and managed very well by all the owners. Over the years thousands of trees have been planted. There are three small lakes on the land, wetlands, wildlife habitats and an equestrian centre. Part of the farm at Ardla has been given over to the County Council and a new graveyard developed there to supplement the ancient Holmpatrick cemetery. .
