Going back to Ancient Times, prior to and during the early part of the first millennium A.D., the Enfield area is believed to have been situated on one of the main roads to Tara, the coronation site and seat of the High Kings of Ireland from the 3rd century until 1022.

[7] When the stagecoach was used as a form of transport in Ireland, this road took a slightly different route to include the area that is now known as Enfield.

[7] A livery stable and courtyard existed opposite the old post office building (now a Chinese restaurant) at the east end of the town, to service people travelling on this road.

The first postal deliveries by stagecoach, in the area, occurred around 1740, during the time of Robert Fitzgerald, 19th Earl of Kildare.

The Royal Canal also passed through Innfield, and with the arrival of the Midland Great Western Railway, the name became anglicised to Enfield.

[3] In 2013, St. Mary's National School was redeveloped and officially opened by Enda Kenny and Bishop Michael Smith of the Meath Diocese.

The stretch from Dublin to Mullingar opened as a trade route around 1807 and the canal eventually reached the Shannon in 1817, though the company was heavily in debt.

The decision by the Duke of Leinster to build a spur from the canal to his country residence at Carton House was one of the contributing factors which finally broke the company.

[citation needed] Both the canal and the railway had stopover points in Enfield, and this contributed to the development of the area.

In 1877, a branch line from Nesbitt Junction (about 2 km (1.2 mi) west of Enfield) to Edenderry was opened.
