It spans the postal districts of Dublin 9 and 11,[citation needed] and is bordered to the northwest by Finglas, northeast by Ballymun and Santry, Whitehall to the east, Phibsborough and Drumcondra to the south and Cabra to the southwest.

His monastery continued to be used for many years afterwards – St. Colman is recorded as having paid homage to its founder when he returned from abroad to visit Ireland a century after St Mobhi's death in 544.

The Battle of Clontarf was fought on the banks of the River Tolka in 1014 (a field called the bloody acre is supposed to be part of the site).

As local rulers continued fighting amongst themselves the Norman King of England Henry II was invited to intervene.

Later, Laurence O'Toole, Archbishop of Dublin, took responsibility for Glasnevin and it became the property of the Priory of the Most Holy Trinity (Christ Church Cathedral).

In a letter, dated 1725 he described Glasnevin as "the receptacle for thieves and rogues [..] The first search when anything was stolen, was there, and when any couple had a mind to retire to be wicked there was their harbour.

When Drumcondra began to rapidly expand in the 1870s, the residents of Glasnevin sought to protect their district and opposed being merged with the neighbouring suburb.

Gradual development of his lands began in 1903/04 but Glasnevin remained relatively undeveloped until the opening up of the Carroll Estate in 1914, which saw the creation of the redbrick residential roads running down towards Drumcondra.

The house and lands of the poet Thomas Tickell were sold in 1790 to the Irish Parliament and given to the Royal Dublin Society for them to establish Ireland's first Botanic Gardens.

Prospect Cemetery is located in Glasnevin, although better known as Glasnevin Cemetery, the most historically notable burial place in the country and the last resting place, among a host of historical figures, of Michael Collins, Éamon de Valera, Charles Stewart Parnell and also Arthur Griffith.

[11] Approaching Glasnevin via Phibsboro is what is known as Hart's Corner but which about 200 years ago was called Glasmanogue, and was then a well-known stage on the way to Finglas.

At the start of the 18th century a large house, known variously as The Glen and later as Delville, was built on the site of the present Bon Secours Hospital, Dublin.

Its name, Delville, was an amalgamation of the surnames of two tenants, Dr. Helsam and Dr. Patrick Delany (as Heldeville), both fellows of Trinity College.

Pope encouraged the Delaneys to develop a garden in a style then becoming popular in England – moving away from the very formal, geometric layout that was common.

He and his lifelong companion Stella were both in the habit of visiting, and Swift satirised the grounds which he considered too small for the size of the house.

Through her correspondence with her sister, Mrs Dewes, Mary wrote of Swift in 1733: "he calls himself my master and corrects me when I speak bad English or do not pronounce my words distinctly".

Patrick Delany died in 1768 at the age of 82, prompting his widow to sell Delville and return to her native England until her death twenty years later.

[citation needed] It served as the parish church until it was replaced, in 1972, by a structure resembling a pyramid when viewed from Botanic Avenue.

[citation needed] In 1975 the new headquarters of Met Éireann, the Irish Meteorological Office, designed by Liam McCormick, opened on Glasnevin Hill, on the site of a former juvenile detention centre, Marlborough House.

[citation needed] The Met Éireann building is a pyramidal shape and was originally to be covered in Welsh Slate, however, an indigenous material was deemed more appropriate, and the selected Irish stone curled and had to be replaced by metal sheeting.

Billy Whelan, one of the eight Manchester United players who lost their lives in the Munich air disaster of 6 February 1958, was born locally and is buried in Glasnevin Cemetery.
