Key takeaways

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

Reference excerpt

The Louvre Pyramid (French: Pyramide du Louvre) is a large glass-and-metal entrance way and skylight designed by the Chinese-American architect I. M. Pei. The pyramid is in the main courtyard (Cour Napoléon) of the Louvre Palace in Paris, surrounded by three smaller pyramids of the same style which also serve as lightwells. The large pyramid serves as the main entrance way to the Louvre Museum, allowing light to the below ground visitors hall, while also allowing sight lines of the palace to visitors in the hall, and through access galleries to the different wings of the palace. Completed in 1989 as part of the broader Grand Louvre project, it has become a landmark of Paris and a symbol of the museum.

Design and construction

The Grand Louvre project was announced in 1981 by François Mitterrand, the president of France. In 1983 the Chinese-American architect I. M. Pei was selected as its architect. The pyramid structure was initially designed by Pei in late 1983 and presented to the public in early 1984. Constructed entirely with glass segments and metal poles, it reaches a height of 21.6 metres (71 ft). Its square base has sides of 34 metres (112 ft) and a base surface area of 1,000 square metres (11,000 ft2). It consists of 603 rhombus-shaped and 70 triangular glass segments. The sides' angle relative to the base is 51.52 degrees, an angle similar to that of ancient Egyptian pyramids. The pyramid structure was engineered by Nicolet Chartrand Knoll Ltd. of Montreal (pyramid structure / design consultant) and Rice Francis Ritchie of Paris (pyramid structure / construction phase). The pyramid and the underground lobby were constructed to address limitations in the Louvre's previous layout, which was no longer capable of accommodating the steadily growing number of daily visitors. Visitors entering through the pyramid descend into the spacious lobby then ascend into the main Louvre buildings. For design historian Mark Pimlott, "I.M. Pei’s plan distributes people effectively from the central concourse to myriad destinations within its vast subterranean network... the architectonic framework evokes, at gigantic scale, an ancient atrium of a Pompeiian villa; the treatment of the opening above, with its tracery of engineered castings and cables, evokes the atria of corporate office buildings; the busy movement of people from all directions suggests the concourses of rail termini or international airports." Several other museums and commercial centers have emulated this concept, most notably the Museum of Science and Industry in Chicago and Pioneer Place in Portland, designed by Kathie Stone Milano with ELS/Elbasani and Logan, Architects from Berkeley, California. The construction work on the pyramid base and underground lobby was carried out by the Vinci construction company.

Aesthetic and political debate over its design

The construction of the pyramid triggered many years of lively aesthetic and political debate. Criticisms tended to fall into four areas:

The modernist style of the edifice being inconsistent with the classic French Renaissance style and history of the Louvre The pyramid being an unsuitable symbol of death from ancient Egypt The project being megalomaniacal folly imposed by then-President François Mitterrand Chinese-American architect I.M. Pei being insufficiently familiar with the culture of France to be entrusted with the task of updating the treasured Parisian landmark. Those criticizing the aesthetics said it was sacrilegious to tamper with the Louvre's majestic old French Renaissance architecture, and called the pyramid an anachronistic intrusion of an Egyptian death symbol in the middle of Paris. Meanwhile, political critics referred to the structure as Pharaoh François' Pyramid. Writing in The Nation, Alexander Cockburn ridiculed Pei's rationale that the structure would help visitors locate the entrance: "What Pei really meant was that in our unfolding fin de siècle, public institutions need an area (...) where rich people can assemble for cocktail parties, banquets and kindred functions, to which the word 'charity' is attached to satisfy bodies such as the IRS." Some still feel the modernism of the edifice is out of place.

Number of panes The pyramid has a total of 673 panes, as confirmed by the Louvre, 603 rhombi and 70 triangles. Three sides have 171 panes each: 18 triangular ones on the edges and 153 rhombic ones arranged in a triangle; the fourth side, with the entrance, has nine fewer rhombic and two fewer triangular ones, giving 160. Some commentators report that Pei's office counts 689. However, a longstanding rumor claims that the pyramid includes exactly 666 panes, "the number of the beast", often associated with Satan. The story of the 666 panes originated in the 1980s, when the official brochure published during construction cited this number twice. The number 666 was also mentioned in various newspapers. One writer on esoteric architecture asserted that "the pyramid is dedicated to a power described as the Beast in the Book of Revelation.... The entire structure is based on the number six." The myth resurfaced in 2003, with the protagonist of the best-selling novel The Da Vinci Code saying: "this pyramid, at President Mitterrand's explicit demand, had been constructed of exactly 666 panes of glass — a bizarre request that had always been a hot topic among conspiracy buffs who claimed 666 was the number of Satan." In fact, according to Pei's office, Mitterrand never specified the number of panes.

Inverted Pyramid

The Inverted Pyramid (Pyramide Inversée) is a skylight in the Carrousel du Louvre shopping mall in front of the Louvre Museum. It looks like an upside-down and smaller version of the Louvre Pyramid.

Renovation Designed for a museum that then attracted 4.5 million visitors a year, the pyramid eventually proved inadequate, as the Louvre's attendance had doubled by 2014. Over the next three years, the layout of the foyer area in the Cour Napoleon beneath the glass pyramid underwent a thorough redesign, including better access to the pyramid and the Passage Richelieu.

Worked examples

Example 1 — a first encounter with Louvre Pyramid

Start with the simplest possible case. Write down what Louvre Pyramid 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 Louvre Pyramid 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 Louvre Pyramid 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 Louvre Pyramid

In research
Louvre Pyramid 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 Louvre Pyramid 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
Louvre Pyramid is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1989 establishments in France, 20th-century architecture in France, Architectural controversies, so understanding it makes those chapters shorter.
In everyday life
Look for Louvre Pyramid 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.
