The Palace of the Parliament stands on Arsenal Hill: 270 by 245 metres, 84 metres above ground and 16 below. Below we raise it together, floor by floor: first the hill with its quarter, then the building site, then the numbers — and at the end the fog of myths, set aside.
today, from the square the palace
A weight, an architect, a fog of numbers
The palace that does not fit in a photo
On Arsenal Hill in Bucharest stands a building 270 by 245 metres: 84 metres above ground, 16 below, 365,000 square metres of developed area. The record book calls it "believed to be" the heaviest building in the world — with "believed", because nobody ever put it on a scale. One weight, one 28-year-old architect, and a fog of numbers around them.
We raise it together, floor by floor: on the left you see the year and what is being built. And at the end we do what no brochure does: we unpick the numbers — which are official, which merely circulate — and set the fog aside.
Where we raise the palace
Bucharest, Arsenal Hill — also called Spirea's Hill — between 2-4 Izvor Street and 1-3 Calea 13 Septembrie. The map below takes you from the country to the palace.
Because the ground gave the reason first: on 4 March 1977, at 21:21, Vrancea shook Bucharest — the palace's official page says 7.2 on the Richter scale and over 1,400 dead, while modern measurements say magnitude Mw 7.4. In Bucharest alone 1,391 people officially died. Post-disaster reconstruction became the plan to flatten the centre and raise something else instead.
The hill had held a quarter: streets, villas, churches. Demolitions for the new centre began as early as 1980, four years before the palace's foundation stone. First came the quake; the palace is the answer laid over it.
The hill · 400 hectares
What was wiped away to fit it?
About 400 hectares of the old centre — a quarter of it — flattened between 1982 and 1989 for the civic centre, with about 40,000 people moved to the outskirts: the figures come from a UCL doctoral thesis, the most serious count found. A variant of 7 square kilometres with 57,000 families also circulates, but with no strong papers behind it — this page shows it as a weak variant, not a fact.
In the palace's direct zone the church count is exact: three demolished — Alba Postăvari on 18 March 1984, Spirea Veche on 27 April 1984, Izvorul Tămăduirii between 4 and 6 August 1984 — and two moved on rails: Schitul Maicilor some 245 metres in June 1982, Mihai Vodă monastery 289 metres and 6.2 metres down in the autumn of 1985, under engineer Eugeniu Iordăchescu. The quarter's story and the moving on rails belong to the sibling page Uranus Hill; here the numbers stay.
The decision · The 28-year-old architect
Who drew the palace?
A 28-year-old architect: Anca Petrescu won the competition that led to the project — the palace's own official page says so. The competition for the new civic centre had begun back in 1977–1978; she drew variants of the House of the Republic in 1981, and in 1983 she was appointed project head by decree. Hundreds of architects worked around her — often reported as about 700, but the figure has no official papers behind it.
The foundation stone was laid on 25 June 1984, according to municipal and press sources; Guinness gives only the year 1984 as the start of construction. And the Ceaușescus read plans with difficulty, so Bucharest was built out of polystyrene: scale models, updated after every visit and instruction. The palace was first drawn small, so it could be commanded large.
The site · 100,000 people
How many people raise a mountain?
Over 100,000 people in total, says the official page: at peak, nearly 20,000 workers in three shifts, day and night, and between 1984 and 1990 some 12,000 soldiers took part too. The floors grew on Arsenal Hill before everyone's eyes — but at the December 1989 Revolution the building was only about 60% finished. Another count says 70% in 1990: this page shows both, with the years in view.
After 1989 the site stopped, then restarted with another purpose: in 1993 the Chamber of Deputies decided to move its activity here, through Decision no. 31 of 16 March 1993, and in 1994 the International Conference Centre was established. 1997 is the conventional completion date — conventional, because fitting-out ran to about 2000 and beyond.

The measures · 365,000 m²
How big is it, with papers?
With official papers, from the palace's page: developed area 365,000 square metres, length 270 metres, width 245 metres, height 84 metres above ground, depth 16 metres below, ground floor 73,615 square metres. And the rooms are about a thousand — some sources say 1,100, with 440 offices and over 30 halls: this page says about a thousand, a thousand one hundred, depending on the source.
Variants circulate around them: 86 metres high, 92 metres below, 330,000 or 340,000 square metres. The official depth is 16 metres — 92 metres is the old variant, still circulating. The palace's lesson: on giant buildings, figures are measured differently by definition, and this page shows them all with the label in view.

The materials · Almost entirely Romanian
What is a weight made of?
Almost entirely from Romania — "almost entirely Romanian", says the official page exactly (the district hall says "entirely only", but our page keeps the cautious wording). The official count: 1,000,000 cubic metres of marble, 550,000 tonnes of cement, 700,000 tonnes of steel, 3,500 tonnes of crystal, 900,000 cubic metres of wood, 200,000 cubic metres of glass, 2,800 chandeliers, 220,000 square metres of carpets.
The marble came from Rușchița, Moneasa, Căprioara and Alun; the chandelier crystal, from Mediaș; the wood — oak, beech, cherry, walnut. And Guinness rests its weight record on materials too: 700,000 tonnes of steel and bronze, a million cubic metres of marble, 3,500 tonnes of crystal, 900,000 cubic metres of wood. The palace's weight was never weighed; it was added up.
The records · With category, not without
What records does it really hold?
Three, with their categories: Guinness no. 1 for administrative buildings for civil use, no. 3 in the world by volume, and — in Guinness's exact wording — "believed to be" the heaviest building in the world. Guinness publishes no total in tonnes: the 4,098,500 tonnes circulating online are a repeated count, not an official weighing. "The largest building in the world", without a category, is too blunt a phrase: records need categories.
The same with money: officially it is called "the most expensive administrative building", but with no clean sum. Circulating are 1.75 billion dollars in 1989, 3 and 4 billion dollars, 3, 3.3 and 4 billion euros — costs, valuations and years all mixed. This page states the wording and shows the fog; it picks no figure.

The myths · The palace itself lists them
What legends does the palace admit to?
The palace keeps an official myths page — and we read it as such, not as facts: the steel cylinder buried in 1984 under the main staircase, with the project's data and a message for the future; the anti-nuclear bunker with escape tunnels; the Union Hall carpet brought in one piece, through the ceiling or through the broken wall; the ceiling that was to open for the presidential helicopter; Ceaușescu's metro to the airport; ghosts in the corridors. All labelled "legend".
What has checked out: regime tunnels existed and were reported — the Washington Post wrote in December 1989 about a network under Bucharest — but the Otopeni airport link is attested in nothing found here. And the "8 underground levels" and "12 levels" are circulating phrases, not official dimensions: the official word says 16 metres below ground. The graded table is further down, at myths.

The afterlife · What never came
What has the palace become today?
The seat of Parliament — the Chamber of Deputies and the Senate — plus the Legislative Council and the Constitutional Court, the International Conference Centre and, in one wing, the National Museum of Contemporary Art. What never came: the presidency, which stayed at Cotroceni although the civic dream wanted it here; and the "Bucharest 2000" competition, which wanted offices all around to soften its impact, shelved around 2000.
"A palace of the megalomaniac, but also a masterpiece of the Romanian people", said Catherine Lalumière, former Secretary General of the Council of Europe, as quoted by the palace's page. To visit, see the palace\u0027s page — here there are no tariffs, only stones.

How do you read a palace from its halls?
Start with the big one: Union Hall has 2,226 square metres and 800–1,000 seats — ceremonies happen here. Next is Human Rights Hall, 484 square metres with 60–150 seats: its name, in a building raised by a totalitarian regime, is a whole history lesson. Then Bălcescu (378 square metres, 150 seats), Iorga (462 square metres, 250 seats), Brătianu (1,120 square metres), Cuza (1,820 square metres, 1,200 seats), Rosetti (1,420 square metres, 600 seats) and the Receptions Salon (1,000 square metres, 550–700 seats).
Do not forget the gallery: the "Constantin Brâncuși" exhibition hall, 1,100 square metres, opened on 15 December 1993 and hosts art exhibitions — a different thing from MNAC, the museum in the palace's wing. A palace reads like a city: the big halls are the squares, the offices are the streets, and the names on the doors are the textbook.
For the classroom: draw the palace's section from the official figures: 84 metres above ground, 16 below, a 270 by 245 metre footprint. Mark Union Hall as a 2,226 square metre rectangle at a scale of your choice. How many of your classrooms fit into one Union Hall?
Who raised the mountain?
A 28-year-old drew it, and over 100,000 people raised it. Anca Petrescu (20 March 1949 – 30 October 2013), the chief architect, won the competition at only 28 and led the design from 1983 to 1989, then the adaptation from 1992 to 2000. At the site's peak, nearly 20,000 workers worked in three shifts, and between 1984 and 1990 some 12,000 soldiers took part too.
The structural design was entrusted in the summer of 1982 to the Carpați Design Institute — lead engineers with proper names do not appear in the open sources used here, and this page says so. The mountain rose with many hands and few signatures: its lesson is that great buildings always have more authors than the frontispiece names.
For the classroom: make the palace's timeline on an axis: 1977 the quake, 1980 the demolitions, 1983 the appointment, 25 June 1984 the stone, 1989 the Revolution (60%), 1993 the Chamber, 1994 the conferences, 1997 the conventional date. Where do you put "finished"? Why is there no single good year?
What is legend and what is on paper?
The palace keeps its own legends, on an official myths page — and this page grades them, as at Bran: the 1984 steel cylinder is legend told by the palace; the bunker with tunnels is legend with an unsolved kernel; the metro to the airport is rumour; the one-piece carpet and the helicopter ceiling are interior legends; the ghosts are the staff's night stories. None of it is presented here as fact.
As for figures: Guinness says "believed to be" and gives the materials, not the total — the 4,098,500 tonnes are a circulating count, not a weighing. The official depth is 16 metres; 92 metres is the old variant. The table grades it in short.

How we worked and what we do not know
The years and facts come from the palace's official pages — the building and the myths — read in full, from the Guinness record page and from two academic works: the official dimensions 365,000 m², 270 by 245 metres, 84 above ground and 16 below, the materials, the 100,000 people, the decision of 16 March 1993, the 400 hectares with 40,000 moved. Where the sources give variants — 86 against 84, 92 against 16, 60% against 70% — this page shows them all with the label in view.
The 3D section is schematic: the floors rise one by one so the phases show, not after the architect's survey, and the myth fog is drawn, not measured. What we do not know yet: the true weight in tonnes, the reconciliation of official 16 metres with legendary 92, how many underground levels exist and in what state, the audited cost, the official room-counting method, and the lead engineers' names. When new papers appear, this page changes.
