The town is located on the picturesque River Slaney and in close proximity to the Blackstairs Mountains and Ireland's longest beach, Curracloe.

The castle houses the Wexford County Museum, which contains extensive 1798 rebellion-related material, as well as items of local and agricultural interest.

Vinegar Hill (Cnoc Fhiodh na gCaor in Irish which translates as 'hill of the berry-tree'), a pudding-shaped hill overlooking the town, was the largest camp and headquarters of the rebels of 1798 who controlled County Wexford for thirty days against vastly superior forces, before their defeat on 21 June.

Following the relaxation of the Penal Laws at the beginning of the 19th century, it became possible for the Roman Catholic community to consider building a cathedral to replace the one in Ferns that had been appropriated for use by the Church of Ireland during the English Reformation.

600 Volunteers took the town, led by Robert Brennan, Seamus Doyle and J R Etchingham, they surrounded the police station but did not attempt to take it.

The government responded by sending a force of more than 1,000 men to retake Enniscorthy and the rebels retired to their positions on Vinegar Hill.

To avoid bloodshed, the army commander Col. F A French offered safe conduct for the Wexford leaders so that they could go to Dublin and hear of the surrender directly from Pearse.

The first successful flight from Britain to Ireland was made from Goodwick's Harbour Village on 22 April 1912 by Denys Corbett Wilson, flying a Bleriot XI.

[7] Enniscorthy is situated by the River Slaney, and has riverside walks beside it to the north and to the south, on the west bank.

It is the cathedral town of the Diocese of Ferns and has two Catholic churches spread over two parishes — St. Aidan's and St Senan's, under the shadow of Vinegar Hill.

[8] Established in 2018, Enniscorthy Arts Trail is an artist led initiative that sees vacant buildings in Enniscorthy town transformed and offered to visual artists as gallery spaces, workshop hubs, and cultural centres during the August Bank Holiday weekend.

Now renamed the Rockin' Food & Fruit Festival, it's the highlight of the summer calendar in Enniscorthy, taking place over the August Bank Holiday Weekend.

[11] The Blackstairs Blues festival is also an annual event and includes international and local performers, in a variety of late-night concerts and workshops.

The Presentation Arts Centre hosts numerous exhibitions per year, with particular emphasis on supporting and promoting emerging artists.

[17] Enniscorthy is the home of the Wexford Carol, a Christmas song dating back to the 16th century or possibly much earlier.

In literature, Enniscorthy is mentioned in the Ithaca chapter of James Joyce's Ulysses (p. 812) as a flyleaf note in a book belonging to Leopold Bloom, where it is described as "Ennifcorthy, County Wexford, the finest place in the world" (sic).

In the story, which is set in the early 1950s, Eilis travels alone from Enniscorthy to Brooklyn because of the lack of opportunities for her at home.

[18] The current economy of Enniscorthy is a mix of sectors including food production (such as Slaney Foods), engineering (such as Aircon Mech), ICT (such as Taoglas), financial services (such as Opus Funds), life sciences (such as Becton Dickinson), hospitality (such as Riverside Park Hotel) and construction (including high performance buildings through the NZEB Training Centre.

[21] Enniscorthy was the location of a regional microbrewery opened in 1864 and owned by the descendants of George Killian Lett.

The Enniscorthy Bypass project, which was officially opened on 18 July 2019, also includes a single carriageway that connects the N30 with the M11, significantly reducing journey times to Waterford.
