Louvre Pyramid Case Study: Plan, Glass and the Hall Below (I M Pei)

The Louvre Pyramid is the glass entrance I. M. Pei designed for the Musée du Louvre in Paris, opened on 29 March 1989 as the visible top of a much larger project: a reception hall dug under the Cour Napoléon that leads to all three wings of the palace. For a case study, the pyramid is only half the building. This one covers the Grand Louvre brief, the site, the plan of the hall below, the cable-braced glass, the debate of the 1980s in dated sources, and what designers in India can take from it.

For the method a jury expects from a building study, see our guide on how to document a building.

The brief and the client: the Grand Louvre

The pyramid answers a museum problem, not a monument problem. In September 1981 President François Mitterrand announced the "Grand Louvre", which would give the whole palace to the museum by taking over the wing occupied by the Ministry of Finance, according to the Louvre's press release for the pyramid's 30th anniversary. The ministry had been in the Richelieu wing since 1871 and used its courtyards as car parks, the Christian Science Monitor reported in November 1993.

Elizabeth Evitts Dickinson, writing in ARCHITECT magazine in April 2017, describes visitors lost in corridors looking for one of only two public toilets. She also notes that Mitterrand picked Pei without an open competition, which angered French architects. The Musée du Louvre dates Pei's appointment to July 1983; ArchDaily's AD Classics entry (Eduardo Souza, 2010) calls him the first foreign architect to work on the Louvre.

By the Louvre's count, the project roughly doubled exhibition space, from 31,000 sq m to over 60,000 sq m.

Site and context: the Cour Napoléon

The Louvre is a U of long wings: Richelieu to the north along the Rue de Rivoli, Denon to the south along the Seine, and Sully round the square Cour Carrée to the east. The open end of the U is the Cour Napoléon. Before Pei, the Louvre says, the court held two small 19th-century gardens by Hector Lefuel and a car park.

Two site facts shaped the design. The axis: because of the bend in the Seine, the pyramid does not line up with the Arc du Carrousel and the historic axis that runs through the Tuileries, up the Champs-Élysées and on to La Défense. The Louvre explains that Pei placed a statue of Louis XIV on that axis in front of the pyramid to tie the two together. The ground: excavation in the Cour Napoléon and Cour Carrée exposed medieval foundations from the reign of Philippe Auguste, and the press release credits the project with leading to the creation of France's national institute for preventive archaeology, Inrap.

Louvre pyramid concept: a landscape, not an object

Pei's idea was a single central entrance. He proposed an underground lobby with direct access to the museum's three wings, the Louvre says, and he described his approach in landscape terms: "My approach was that of a landscape designer rather than an architect." He named André Le Nôtre, the 17th-century garden designer, as his main inspiration. The square and the triangle repeat from the pyramid into the pools and the paving of the court.

Why a pyramid? A few reasons appear in the sources:

• Transparency. Pei wanted sides clear enough to see the old facades through them, from inside and out (Louvre). Flynn told ARCHITECT that Pei "wanted no color".
• A sign for the entrance. In October 1984 the Christian Science Monitor (Jonathan Fenby) quoted Pei calling it "a luminous structure-symbol". ArchDaily says he called it "a work of our time".
• Size from the programme. Flynn again: "The program informed the pyramid's size."
• Geometry. ArchDaily says its proportions follow the Great Pyramid of Giza; Structurae gives the face slope as 51.52°. We found no primary source for the "golden ratio" claims online.

Louvre pyramid floor plan and zoning

Read the plan in two layers. At court level there are only glass objects: the main pyramid at the centre, three small pyramids that the Louvre says light the passages to the three wings, and triangular pools. Below the court is the real building. The Louvre lists what Pei put under the ground: the reception hall, ticket office, auditorium, cafés, bookshops, underground storerooms, and a shopping centre connected to the nearest metro station. He also designed new galleries in the Richelieu wing.

The hall below: circulation as the main idea

The zoning is a hub and spokes. Visitors enter the pyramid at court level and go down into the hall, where tickets, information and services sit, then choose a wing. Texas Tech University's architecture image archive describes the lobby under the pyramid with a self-supporting helical stair and a hydraulic lift at its centre. The second phase added a route west under the Carrousel, lit by an inverted pyramid of 84 diamond and 28 triangular panes (Louvre), which the Monitor reported open in October 1993.

Phase II: the Richelieu wing, 1993

The Richelieu wing opened as galleries in November 1993, for the museum's bicentenary, according to Wilmotte & Associés, which lists Pei and Michel Macary as architects. The Monitor says Macary handled much of the ground floor, including the glass-roofed courtyards that once held the ministry's cars.

Where to see the real drawings

Our diagrams do not trace any published drawing. Pei Cobb Freed & Partners present the project on their website, and the Texas Tech archive above holds views of the hall. For what a full drawing set should contain, see our guide to a complete set of architectural drawings.

Louvre pyramid section and structure

In section, the pyramid is a lid over an opening in the court slab, lighting a hall that runs well beyond its base.

The structure is a stressed frame behind the glass. The Louvre's figures are 6,000 bars and girders and 2,150 nodes, with 95 tonnes of steel structure and 105 tonnes of glazed aluminium frame. The metal frame was built with companies that specialised in ships' rigging, the Louvre says. Ian Bader told ARCHITECT that much time went into "the design of the cables and counter-cables" and the glass. Flynn added a detail worth noting: "We doubled the weight of the glass to put more load on the pyramid structure to keep it stable." Structurae credits Nicolet Chartrand Knoll of Montreal as design consultant and RFR of Paris for the construction phase.

Louvre pyramid materials and construction details

• Glass: 2,000 sq m of 21 mm glazing made by Saint-Gobain, after two years of research to get an extra-clear glass, according to the Louvre.
• Panes: the Louvre gives 675 diamond-shaped and 118 triangular panes. Structurae, citing the Louvre, gives 603 and 70 (673 in all) and notes that other counts circulate. We report both; we could not settle it.
• Frame: steel members and cables, with an aluminium glazing frame. Pei wanted the frame to match the palace roofs, and Flynn told ARCHITECT the team found 11 different shades of grey on them.
• Build: Structurae names Vinci for the base and the underground lobby.

Light, climate and services

The pyramids' environmental job is daylight for a hall that would otherwise be a basement. The weak point is the crowd. The Louvre's 2016 release on the "Pyramid Project" says the entrance was designed for 4.5 million visitors a year and, about 25 years later, was receiving close to 10 million, with long queues and noise. The 2014 to 2016 works moved ticketing, cloakrooms and toilets to the edge of the hall, added sound-absorbing partitions that the release says cut noise and heat, and doubled access control at the entrance. The museum gives the cost as €53.5 million and credits the design to museum staff with the architecture firm Search.

Louvre pyramid controversy: reception in dated sources

The Louvre's own "A transparent controversy" page says the pyramid caused controversy in the press and the National Assembly during construction from 1985 to 1989. In order:

• October 1984. The Monitor reported that the French commission for historic monuments had voted against the project by 60 percent to 40 percent, and that former culture minister Michel Guy opposed it.
• In the press. Le Monde's critic André Fermigier called it a "foreign body, showing such disregard for history", as Vincent Noce recalled in The Art Newspaper on 29 March 2019; Noce adds that Le Figaro dismissed it as a "gadget". ARCHITECT cites a 1985 New York Times story that gathered critics' words, including "an architectural joke, an eyesore".
• The mock-up. Bader told ARCHITECT the most pivotal moment was a full-scale mock-up of the pyramid in the courtyard for Jacques Chirac, then mayor of Paris. In June 1988 the Monitor (William Echikson) reported that Chirac, who had promised to cut the budget, changed his mind after a close look; an aide said he "was seduced".
• Pei's view. In a PBS documentary quoted by ARCHITECT, Pei said 90 percent of the public were against the idea at first, and that the first year and a half "was really hell".
• Since 1989. Noce credits the pyramid with helping lift visitors from 3.5 million in 1989 to more than 10 million in 2018. The American Institute of Architects gave the Grand Louvre Phase I its 2017 Twenty-five Year Award, ARCHITECT reported in December 2016.

Cost. Press figures changed with scope: 2 billion francs (Monitor, 1984), $800 million (1988) and $1.2 billion for Pei's ten-year project (1993).

Where sources disagree. Height: 21 m (Louvre, "A pyramid for a symbol"), 19 m (Louvre, "A transparent controversy"), 21.64 m (Structurae), 22 m (The Art Newspaper) and 71 ft, about 21.6 m (ARCHITECT). Base: 35 m (Louvre) or 34 m a side (Structurae). The hall works: 2014 to 2016 (Louvre) or 2014 to 2018 (The Art Newspaper).

What comes next. In early 2025 the French president announced a new plan for the museum. The Louvre's "Louvre Nouvelle Renaissance" competition page says a team led by STUDIOS Architecture Paris and Selldorf Architects, with BASE Landscape Architecture, was chosen in May 2026 to design two new entrances at the eastern end, by the Colonnade, one on the Seine side and one on the Rue de Rivoli side.

What designers in India can take from it

This is our reading for Indian practice, not a claim made by the sources above.

1. Put the service programme under the setting. At many Indian heritage sites, ticket counters and toilets end up as sheds in front of the monument. The Louvre moved all of them under the court and left one glass marker above. Where the water table and budget allow, a sunken forecourt or a basement does the same. Budget for waterproofing, pumping and archaeology: the Louvre's own dig turned up medieval walls.
2. Size entrances for the crowd you will get, not the one you have. An entrance planned for 4.5 million visitors had to be rebuilt within about 25 years, and new entrances are now being added. For a museum, campus or station, plan a second entrance and queue space from day one.
3. Do not copy a glass pyramid into Indian sun. A large glazed skylight suits Paris and still added heat and noise to the hall. In most Indian climates, bring daylight in through shaded, north-facing or diffusing openings, and put glass where it can be shaded. Our green building certification guide covers how rating systems treat glazing and daylight.
4. Use full-scale mock-ups to win approvals. A courtyard mock-up changed a mayor's mind. A facade bay, a jaali panel or a string outline on site costs little next to a committee's "no".

Visiting the Louvre Pyramid

The pyramid is the main entrance of the Musée du Louvre, Paris 1er. The Louvre's hours and admission page gives museum hours of 9 am to 6 pm on Monday, Thursday, Saturday and Sunday and 9 am to 9 pm on Wednesday and Friday, closed on Tuesdays and on 1 January, 1 May and 25 December. The Cour Napoléon itself is open from 7.30 am to 9 pm, so you can study the pyramid, pools and axis from the court. It lists tickets at €22 for European Economic Area visitors and €32 for others, free for under-18s, and recommends booking a time slot. Check before you travel.

We use diagrams rather than photos here. Wikimedia Commons' freedom of panorama guide marks France as having no freedom of panorama for buildings, and Pei died in 2019, so his design stays in copyright.

FAQ

Who designed the Louvre Pyramid?

I. M. Pei of Pei Cobb Freed & Partners, appointed in July 1983. Structurae credits Nicolet Chartrand Knoll of Montreal and RFR of Paris for the structure, and the Louvre says Saint-Gobain made the glass.

When was the Louvre Pyramid built?

Works ran from 1985 to 1989, and President Mitterrand inaugurated the pyramid on 29 March 1989, according to the Louvre. The second phase, with the inverted pyramid and the Richelieu wing, followed in 1993.

What is the Louvre Pyramid made of?

Glass on a metal frame: 2,000 sq m of 21 mm extra-clear glass by Saint-Gobain, 95 tonnes of steel structure braced with cables, and 105 tonnes of glazed aluminium frame, by the Louvre's figures.

How tall is the Louvre Pyramid and how many glass panes does it have?

The Louvre gives 21 m high and 35 m wide at the base, with 675 diamond-shaped and 118 triangular panes. Other sources give 19 m to 22 m for the height and 673 panes in all.

Why was the Louvre Pyramid controversial?

Critics saw a modern glass form as wrong for a historic palace, and French architects objected that there was no competition. The historic monuments commission voted against it in 1984, and Le Monde's critic called it a "foreign body". A full-scale mock-up helped win over Jacques Chirac.
