The Newtown Monuments consist of a large medieval cathedral, two monasteries and small church which date from 1206.

The descriptions that I have seen are a bit confusing in that most of them are different to a lesser or greater degree.

My current understanding is that the main building is the Church of St Peter and St Paul (sometimes called a cathedral). The smaller church in the east of the monastery is the parish church of Newtown Clonbun. This is the burial site of Lucas Dillon (c. 1530 – 1592), Attorney General for Ireland and Chief Baron of the Irish Exchequer, and his first wife Jane Bathe. There is also a ’Tower House’ and a ‘Refectory’

The medieval cathedral [Cathedral and Priory Of Saints Peter and Paul] is situated in Newtown Cemetery. It was founded close to the temporal power of Trim Castle by the Norman Bishop Simon de Rochfort in c.1206 after his cathedral at Clonard was burned down. Only part of the original nave and chancel of this largest Gothic Church in Ireland survive. Part of the ruined Priory of Augustinian Canons, which were established to maintain the Cathedral, also survive.

Buried under the high alter of the cathedral are the remains of the founder Simon de Rochford (died 1224) and one of his successors, Bishop William Sherwood, who died in 1428.

The figure of the bishop now affixed to the wall of the cathedral was long trodden underfoot and was badly worn in places. The figure is commonly known as ‘king john's daughter' but is probably the figure of Simon de Rochford the founder of the cathedral.

In the parish church in Newtown-Clonbun stands the remains of the tomb of Sir Lucas Dillon and his wife Lade Jane Bathe, daughter of James Bathe of Athcarne and Drunmconrath. The recumbent figures of Sir Lucas in Renaissance armour and his wife in Elizabethian gown surmount the tomb. This tomb is known locally as the
tomb of the jealous man and woman because the two figures do not touch each other at all. And also the sword of state separates the figures.
