How high is Montjuïc? No institution in Barcelona will tell you

Here is a question with no answer, and the shape of the missing answer is more useful than most facts.

How high is Montjuïc?

You will find 173 metres. You will also find 177. Both circulate widely, in guidebooks and on maps and in the confident middle paragraph of a great many articles.

We went looking for an institution that publishes either. We did not find one.

What we looked at

The Ajuntament’s pages for the hill’s parks and viewpoints describe slopes, sectors, levels and hectares of garden without giving a summit altitude. The page for the Mirador del Migdia, for instance, is precise about everything except height: it occupies one of the last sectors that remained to be urbanised at the end of the twentieth century on the southern flank of the mountain of Montjuïc, and it was planned at the same time as the Olympic Ring of the 1992 Games was designed. Slope, sector, decade. No metres.

The Generalitat’s geographic institute returns Montjuïc as a neighbourhood, not as a summit with a spot height.

And the Gran Enciclopèdia Catalana has an entry called Montjuïc, which is where this gets interesting.

The trap

The encyclopaedia’s entry at that address reads, in its entirety:

Summit of the municipality of Pinós (Solsonès).

A different mountain, inland, a hundred kilometres away, sharing the name. And it gives no altitude either, so citing it would be doubly useless: the wrong hill and no number.

⚠️ We flag this because it is exactly the sort of citation that looks impeccable. A national encyclopaedia, an entry with the right name, a URL that resolves. Anyone checking a footnote in a hurry would pass it.

⚠️ And it happens twice on this hill. The same encyclopaedia’s entry for font del Gat is a fountain in Camarasa, in the Noguera — not the famous one in the Laribal gardens. Two of the most searched names on Montjuïc resolve, in the standard reference work, to somewhere else.

The one height that is published, and it is not the summit

There is exactly one vertical figure for this hill that an institution stands behind, and it belongs to a lighthouse.

The Port de Barcelona, on the Montjuïc light:

built at 108 metres above sea level, the new lighthouse achieved a luminous range greater than the one the Llobregat lighthouse provided, situated at sea level.

Twenty-six nautical miles of range from 108 metres of elevation.

That number exists because it has to. A light’s height above the water determines how far away a ship can see it, so it is an operational specification, published and checkable. Nobody has the same obligation to publish where the top of the hill is.

⚠️ Do not turn the 108 into the summit. The lighthouse is on the south-east flank, below the castle, above the port. It is a different place and a lower one.

The other missing number: how big is it

Same story.

This site used to publish a figure of 376 hectares for the area of Montjuïc. We could not source it. We retracted it, and it now sits on our internal list of withdrawn claims — a list a script runs against every page of the live site after every deployment, precisely so that a retracted number cannot creep back in through a new article written by somebody who had not read the retraction.

We have never been able to replace it. The Ajuntament’s own pages for the Parc de Montjuïc do not give a total. So there is currently no area figure on this site for the biggest green space in Barcelona, and there will not be one until we can open a page that says it.

The Port has the same problem with itself, incidentally: it publishes two different surface areas for the port on two of its own pages, one qualified and one not.

The one thing about this hill that is not in doubt

It is worth saying clearly, because the pattern of this article could give the wrong impression.

The name is settled. Montjuïc is named after the Jewish cemetery on it. The decree declaring the necropolis a cultural asset says the cemetery gives its name to the mountain; the documentation preserved from 878 onwards calls the hill Mons Judaicus, consistently; and the Mons Iovis derivation is treated by the reference sources as a dispute among older authors that the documents settle.

This site got that wrong once, in the other direction — we published the name as an open question, and it is not. The cemetery is its own subject, and it is one where the sources are unusually solid.

So the position is not “nothing about Montjuïc can be known”. It is narrower and stranger: the history is well documented and the dimensions are not.

What to say instead of a number

If you want to describe this hill accurately without inventing a figure, use what is sourced:

It is made of sandstone, and the city ate it. Most of the singular buildings of Barcelona came out of these quarries — the Roman wall, the cathedrals, the Drassanes, the Sagrada Família, in whole or in part.

It made the ground the city stands on. A good part of Barcelona is built on sand this hill put there.

The gardens are in the holes. Costa i Llobera, Mossèn Cinto Verdaguer and the historic botanical garden are all in worked-out quarries. So is the Greek Theatre.

And it is high enough to matter for navigation, which is the only claim about its height anyone has needed to write down.

That is a better description of a mountain than three digits.

Where this sits on the hill

If you want to feel the height rather than read it, walk up from Plaça d’Espanya through the Laribal gardens instead of riding the escalators, and come down over the seaward flank past the Mirador de l’Alcalde. The full set of ways up and down is here, including which of the three cable-car-shaped things you actually want.

Our Montjuïc walk runs Tuesday and Thursday afternoons, and we will happily tell you what we do not know. We are closed on 25 December and 1 January.
