Nelson's Pillar

Nelson's Pillar is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nelson's Pillar rather than just read about it. In short: Nelson's Pillar (also known as the Nelson Pillar or simply the Pillar) was a large granite column capped by a statue of Horatio Nelson, built in the centre of what was then Sackville Street (later renamed O'Connell Street) in Dublin, Ireland. Completed in 1809 when Ireland was part of the United Kingdom, it survived until March 1966, when it was severely damaged by explosives planted by Irish republicans.

Key takeaways

  • Nelson's Pillar belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Nelson's Pillar to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Nelson's Pillar from memory before moving on to harder problems.

Reference excerpt

Nelson's Pillar (also known as the Nelson Pillar or simply the Pillar) was a large granite column capped by a statue of Horatio Nelson, built in the centre of what was then Sackville Street (later renamed O'Connell Street) in Dublin, Ireland. Completed in 1809 when Ireland was part of the United Kingdom, it survived until March 1966, when it was severely damaged by explosives planted by Irish republicans. Its remnants were later destroyed by the Irish Army. The decision to build the monument was taken by Dublin Corporation in the euphoria following Nelson's victory at the Battle of Trafalgar in 1805. The original design by William Wilkins was greatly modified by Francis Johnston, on grounds of cost. The statue was sculpted by Thomas Kirk. From its opening on 29 October 1809 the Pillar was a popular tourist attraction, but provoked aesthetic and political controversy from the outset. A prominent city centre monument honouring an Englishman rankled as Irish nationalist sentiment grew, and throughout the 19th century there were calls for it to be removed, or replaced with a memorial to an Irish hero. It remained in the city as most of Ireland became the Irish Free State in 1922, and the Republic of Ireland in 1949. The chief legal barrier to its removal was the trust created at the Pillar's inception, the terms of which gave the trustees a duty in perpetuity to preserve the monument. Successive Irish governments failed to enact legislation overriding the trust. Although influential literary figures such as W. B. Yeats and Oliver St. John Gogarty defended the Pillar on historical and cultural grounds, pressure for its removal intensified in the years preceding the 50th anniversary of the Easter Rising, and its sudden demise was, on the whole, well received by the public. Although it was widely believed that the action was the work of the Irish Republican Army (IRA), the Garda Síochána were unable to identify any of those responsible. After years of debate and numerous proposals, the site was occupied in 2003 by the Spire of Dublin, a slim needle-like structure rising almost three times the height of the Pillar. In 2000, a former republican activist gave a radio interview in which he admitted planting the explosives in 1966, but after questioning him the Gardaí decided not to take action. Relics of the Pillar are found in Dublin museums and appear as decorative stonework elsewhere and its memory is preserved in numerous works of Irish literature.

Background

Sackville Street and Blakeney

The redevelopment of Dublin north of the River Liffey began in the early 18th century, largely through the enterprise of the property speculator Luke Gardiner. His best-known work was the transformation in the 1740s of a narrow lane called Drogheda Street, which he demolished and turned into a broad thoroughfare lined with large and imposing town houses. He renamed it Sackville Street, in honour of Lionel Sackville, 1st Duke of Dorset, who served as Lord Lieutenant of Ireland from 1731 to 1737 and from 1751 to 1755. After Gardiner's death in 1755 Dublin's growth continued, with many fine public buildings and grand squares, the city's status magnified by the presence of the Parliament of Ireland for six months of the year. The Acts of Union of 1800, which united Ireland and Great Britain under a single Westminster polity, ended the Irish parliament and presaged a period of decline for the city. The historian Tristram Hunt writes: "[T]he capital's dynamism vanished, absenteeism returned and the big houses lost their patrons". The first monument in Sackville Street was built in 1759 in the location where the Nelson Pillar would eventually stand. The subject was William Blakeney, 1st Baron Blakeney, a Limerick-born army officer whose career extended over more than 60 years and ended with his surrender to the French after the siege of Minorca in 1756. A brass statue sculpted by John van Nost the younger was unveiled on St Patrick's Day, 17 March 1759. Donal Fallon, in his history of the Pillar, states that almost from its inception the Blakeney statue was a target for vandalism. Its fate is uncertain; Fallon records that it might have been melted down for cannon, but it had certainly been removed by 1805.

Trafalgar

On 21 October 1805, a Royal Navy fleet commanded by Vice-Admiral Lord Nelson defeated a combined fleet of the French and Spanish navies at the Battle of Trafalgar. At the height of the battle Nelson was mortally wounded on board his flagship, HMS Victory; by the time he died later that day, victory was assured. Nelson had been hailed in Dublin seven years earlier, after the Battle of the Nile, as defender of the Harp and Crown, the respective symbols of Ireland and Britain. When news of Trafalgar reached the city on 8 November, there were similar scenes of patriotic celebration, together with a desire that the fallen hero should be commemorated. The mercantile classes had particular reason to be grateful for a victory that restored the freedom of the high seas and removed the threat of a French invasion. Many of the city's population had relatives who had been involved in the battle: up to one-third of the sailors in Nelson's fleet were from Ireland, including around 400 from Dublin itself. In his short account of the Pillar, Dennis Campbell Kennedy considers that Nelson would have been regarded in the city as a hero, not just among the Protestant Ascendancy but by many Catholics among the rising middle and professional classes. The first step towards a permanent memorial to Nelson was taken on 18 November 1805 by the city aldermen, who after sending a message of congratulation to King George III, agreed that the erection of a statue would form a suitable tribute to Nelson's memory. On 28 November, after a public meeting had supported this sentiment, a "Nelson committee" was established, chaired by the Lord Mayor. It contained four of the city's Westminster MPs, alongside other city notables including Arthur Guinness II, the son of the brewery founder. The committee's initial tasks were to decide precisely what form the monument should take and where it should be put. They had also to raise the funds to pay for it.

Worked examples

Example 1 — a first encounter with Nelson's Pillar

Start with the simplest possible case. Write down what Nelson's Pillar claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nelson's Pillar before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nelson's Pillar ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nelson's Pillar

In research
Nelson's Pillar appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Nelson's Pillar in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Nelson's Pillar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1809 establishments in Ireland, 1966 disestablishments in Ireland, Buildings and structures completed in 1809, so understanding it makes those chapters shorter.
In everyday life
Look for Nelson's Pillar outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
