At an early date, a monastery was founded at Trim, which lay within the petty kingdom (tuath) of the Cenél Lóegairi. It is traditionally thought to have been founded by St. Patrick and left in the care of its patron saint Lommán, also locally known as Loman, who flourished sometime between the 5th and early 6th century. When domestic politics endangered the position of Lommán's foundation, the church of Armagh assimilated Lommán into the dossier of St. Patrick, making him a disciple of that saint. Attackers burned the church several times in the twelfth century, during which it was refounded as an St. Mary's Abbey under Augustinian rule. The abbey church was the sanctuary for "Our Lady of Trim", a wooden statue reported to work miracles. The statue made Trim a major pilgrimage site from at least 1397. During the Reformation the statue was burned and Henry VIII dissolved the abbey. The abbey's bell tower, the "Yellow Steeple", is the primary remnant of St. Mary's.
With the spelling "Áth Truim", the bishopric is today listed by the Catholic Church as a titular see. Since it is not mentioned in either of the lists of the reduced number of sees approved by the Synod of Ráth Breasail (1111) and the Synod of Kells (1152), it was one of the monastic establishments that were no longer recognized as seats of bishops after the 12th-century reorganization of the Church in Ireland. Its territory was joined to that of Meath Diocese.
Lying 61 m above sea level on the River Boyne, Trim became one of the most important Hiberno-Norman settlements in the Middle Ages. In the 15th century the Norman-Irish parliament met in Trim. Arthur Wellesley, 1st Duke of Wellington is reputed to have been born in Dangan Castle between Trim and Summerhill, and a large column to him was erected in the town in 1817. The town's main feature is Ireland's largest Norman castle, Trim Castle; other features include two ruined church complexes, the Boyne River for fishing, and the Butterstream Gardens, visited by Charles, Prince of Wales in the mid-nineties (no longer open to the public).
Trim Castle (or King John's Castle) is Ireland's largest Norman castle. It was built in the late 12th century following the Norman invasion of Ireland. Trim and the surrounding lands were granted to Hugh de Lacy, Lord of Meath, a Norman baron. Richard II of England stayed there before being ousted from power. Once a candidate to be the country's capital, the town has also occupied a role as one of the outposts of the Pale, and sessions of the Irish Parliament were sometimes held here, as in 1542. It was also designated by Elizabeth I of England as the planned location for a Protestant Dublin University (known as Trinity College, Dublin). However this was revised by Sir Francis Drake, who advocated the case for locating the University in Dublin. In 1649 after the sacking of Drogheda, the garrison of Trim fled to join other Irish forces and the town was occupied by the army of Oliver Cromwell. There were many local disturbances in neighbouring villages in the Irish Rebellion of 1798, most infamously the battle on the Hill of Tara, following the dispersal of the Wexford rebellion. Trim was represented by Arthur Wellesley in the Irish Parliament from 1790 to 1797.
The 19th century saw the construction of Trim Courthouse, St. Loman's Catholic church, St. Patrick's Anglican church, the Wellington column, the current Bank of Ireland building, and Castle Street by Lord Dunsany, a major landowner. Following the Great Irish Famine of 1846–1849, the practices of agriculture in the hinterland altered, with a change in emphasis from tillage to stock raising. This resulted in a change in the business life of Trim. Trim developed as a market town for the productive agricultural hinterland. Some small-scale local industries were developed including envelope, and leather product manufacturing. Trim was also chosen as location for the Timoney Engineering company to make Fire Tenders. However, in the main the town continued to mainly be a service centre for its immediate area.
During the Irish War of Independence, local companies of the Irish Republican Army took Trim RIC Barracks, a large structure located on the current site of the Castle Arch Hotel, secured the arms from the barracks and then burnt down the Barracks. A large part of the town was burned as a reprisal by the British Crown forces on 26 September 1920. The local members were drawn from Trim, Longwood, Ballivor and South Meath in general. The Lalor brothers form Castle St. were prominent members as well as the Duignans from High St and the Proctors. Records of the adventures of the Lalors rest in Navan library and recount the tales of one of the brothers hiding in the recently dug grave of Fr. Woods in the churchyard. Local memories recall the townspeople sheltering down by the Boyne for a few nights as the Black 'n' Tans and Auxiliaries burnt out prominent businesses and the town hall. Footage of the burning of J&E Smyth can be viewed on the 'Pathe' website. Many of the townspeople were traumatised for the rest of their lives; many children in Trim were not allowed to play with guns; memories of the B'n'Ts dangling grenades outside their windows as the Town Hall burnt and peeled the paint off their doors at Castle St. remained for a long time. The newspapers reported the burning of the barracks and the subsequent looting and burning of the town and follow-up operations by the local IRA.
In later years the Lalors who moved to the house across the road from the old Brothers school had a collection of memorabilia from those years including, letters from Collins sent from Frongoch (they kept the originals and forward duplicates to HQ), Devs slippers and a Tricolour made by Constance Markievicz (with her name embroidered) that was to fly over the GPO during the Rising. Their whereabouts now are unknown but photographs of their existence are on file in Navan library. While other parts of Meath were particularly quiet during the War Of Independence, the men from South Meath took the war to the British; one ambush by one of the Lalor brothers took place at the Wellington Monument, where he single-handedly took on a truckload of British with his rifle and grenade, the monument to the British PM still stands.
A new bridge was built on the Boyne in the 1980s to divert heavy traffic from the town. This was then enhanced by the construction, in stages, of an inner relief road, which now makes it possible for heavy traffic to achieve a complete by-pass of the town. The Watergate bridge was replaced in 2005. The local town council purchased a field beside the new bridge in 2004, as it was expected to be of archaeological significance.
As part of the Civil Service decentralization plan of the Irish government, Trim was chosen as the location of the headquarters for the state body known as the Office of Public Works. The movement of this state administration function to Trim resulted in Trim being the first location outside of Dublin to complete a satisfactory decentralization move. Trim has seen some growth in recent years with growth as a tourist and business centre.St Patrick's church (Roman Catholic), Church Street
