Calpe Conference 2026: Neanderthals, and the Child Found a Hundred Years Ago

23 June 2026 Last checked 2026-06-23

The 30th Calpe Conference ran 2 to 5 September 2026 at the University of Gibraltar, drawing 61 institutions from 16 countries, built around the centenary of the Devil's Tower child.

A hundred years ago, in June 1926, an archaeologist lifted five fragments of a child's skull out of a rock shelter at Devil's Tower, on the north front of the Rock. The thirtieth Calpe Conference was built around that child.

Calpe is the Gibraltar National Museum's annual gathering on human evolution and the territory's most serious academic event. The 2026 edition ran from Wednesday 2 to Saturday 5 September at the University of Gibraltar under the title Neanderthal: The Conference. It has now taken place. This page was rewritten on 3 November 2026 to record what it was, with sources, rather than what was expected of it.

What Calpe 2026 was

The thirtieth Calpe Conference opened at 9am on Wednesday 2 September 2026 and ran four days at the University of Gibraltar, organised by the Gibraltar National Museum and opened by the Minister for Heritage, Professor John Cortes. The stated aim was not a showcase but a stocktake: an up to date state of the question analysis of what is actually known about Neanderthals.

The scale is worth getting right, because the published figures moved. The museum's own call material and the Government's June announcement said around fifty academic institutions from fourteen countries. By the time delegates arrived, the Government's welcome release and the Gibraltar Chronicle both put it at 61 institutions from 16 countries. An earlier version of this page carried the fifty and fourteen. The higher figure is the one that describes the conference that actually happened.

Entry is by registration and is free to Gibraltar residents, as it has been for years, with a separate form for non residents. That is the detail most worth knowing locally. A four day international conference on human evolution, in your own town, at no cost, is not a normal thing for a territory of 37,936 people to have.

The name is older than the conference. Calpe, or Mons Calpe, is the ancient name for the Rock itself, the northern of the two Pillars of Hercules that marked the edge of the classical world. Naming a conference on human evolution after the classical limit of the known world is a better joke than the museum usually gets credit for.

A stocktake was also well timed. Ancient DNA has moved faster than the textbooks for two decades, and much of what was settled about Neanderthal behaviour, diet and interbreeding when these conferences started has since been revised or overturned. A state of the question review is more useful in that situation than another round of new results, because it forces the field to say what it currently believes rather than what it most recently published.

The centenary at the heart of it

On 11 June 1926 Dorothy Garrod, later the first woman to hold a professorship at Cambridge, excavated a rock shelter at Devil's Tower and recovered the skull fragments of a Neanderthal child. The specimen is Gibraltar 2. Garrod called it Abel. It is now known as Flint.

The child was about four or five years old, and DNA work published in 2019 established that this one was a boy. Treat any single age figure with care: early estimates ran from about four to between six and eight, and the sources still differ, with the Government release calling him four years old and other accounts saying five. The skull was fractured when found, and a long argument about whether the fragments came from one child or two was settled in favour of one.

Both Gibraltar skulls live at the Natural History Museum in London. What you can see on the Rock are the replicas and the reconstructed faces at the Gibraltar National Museum. The forensic reconstructions of both, by the Dutch palaeoartists Kennis and Kennis, were revealed in 2016 after around eighteen months of work, which makes 2026 ten years since the Rock's two Neanderthals got faces.

For the conference itself the museum commissioned a new image of Flint from the palaeoartist Mauricio Anton, and that image carried the poster and the programme. The opening session was Dr Alex Menez on Gibraltar, Dorothy Garrod and the Devil's Tower skull, and his book on the same subject was launched the evening before, on Tuesday 1 September at 6.30pm at the museum.

The Rock has produced two Neanderthal faces: an adult woman blasted out of a quarry in 1848, and a small boy brushed out of a rock shelter in 1926. One conference, thirty years old, exists largely because of them.

Who actually spoke

The programme was not a local affair with visiting guests. Press coverage and the Government announcement name a bill that would hold up anywhere: Chris Stringer of the Natural History Museum, Ian Tattersall of the American Museum of Natural History, Tom Higham of Vienna, Matthias Meyer, John Murray of Galway, Peter Sahlins, and Stewart and Clive Finlayson of the Gibraltar National Museum. Clive Finlayson gave the closing talk on the Saturday afternoon.

The week also carried the international premiere of the documentary The Last Traces of the Neanderthals, and GBC reported the conference's focus on Neanderthal children specifically, which is the thread the centenary pulled on.

Why Gibraltar matters for this science

The Rock's claim does not rest on the conference. It rests on a run of discoveries going back nearly two centuries. In 1848 a quarry blast on the north face loosened a near complete adult skull at Forbes' Quarry, one of the earliest Neanderthal fossils ever found, and nobody at the time had a framework to understand it. We tell that story, including the name the Rock nearly gave the whole species, in our guide to the Forbes Quarry skull.

Then there are the caves on the eastern side. The Gorham's Cave Complex was inscribed on the UNESCO World Heritage List in 2016, which made 2026 its tenth anniversary and the second of the conference's two anniversaries. What the caves hold is not just occupation layers but evidence of behaviour, including the crosshatch engraving cut into the bedrock that we cover in our piece on the Gorham's Cave engraving.

That combination is why the field comes here. Few places have both the fossils and the living sites, and fewer still have them inside seven square kilometres.

Calpe 2026 at a glance

What you can see of this for yourself

Start at the Gibraltar National Museum in the town centre. The casts, the reconstructed faces and the prehistory collections are there, and without that context the rest of it is just scenery. Budget more time than you think.

Be realistic about the sites themselves. Devil's Tower is not a visitor attraction. It is a rock shelter on the north front, near the road that carries the same name, and there is nothing laid on for the public. Gorham's Cave is a World Heritage Site with restricted access rather than a turnstile. The honest advice is to see the north face from the ground, look at where Forbes Quarry sits, and get the actual material at the museum.

The upper Rock is a different proposition and worth the day on its own, for the limestone, the Strait and the view to Africa that shaped the environment all of this happened in. Our Rock of Gibraltar guide covers the practical side of that.

What is not known about Calpe 2027

No theme or dates for the 2027 conference have been announced. There is a pattern rather than a promise: Calpe runs annually and has settled into early September, and the themes move around a good deal. The 29th conference in 2025 was about Gibraltar in the Second World War and other global conflicts, which is as far from Neanderthal genetics as the series gets.

So do not assume a second Neanderthal year. If you want to attend, watch the Gibraltar National Museum's news pages from around late spring, which is when the call for papers and the registration forms have gone up in recent years.

Practical notes for delegates

Getting here is easier than the map suggests. The airport sits on the frontier with Spain, and many delegates arrive overland through the surrounding region; our guide to getting to Gibraltar by air, road or the border covers the options, including the fact that routine passport checks at the Spanish frontier ended on 15 July 2026.

Early September is a good time to be here. Days are warm without the peak of August, evenings are long, and the town is busy because National Day falls on 10 September, the week after Calpe usually sits. Our month by month guide sets the weather in context. For evenings, Grand Casemates Square and the lanes around it hold most of the restaurants, and our food and drink guide is the shortcut.

Where to stay for the Calpe Conference

A four day conference is a different stay from a weekend break. Delegations arrive together, stay several nights and often want to eat at their own hours rather than a dining room's. That suits an apartment better than a room: a full kitchen, a washing machine, a Smart TV, and self service check in for the ones who land late.

Victory Suites is 100+ apartments on Devils Tower Road, which is a coincidence worth naming. The road takes its name from the same Devil's Tower as the rock shelter where Garrod found the child in 1926, so anyone staying on that road during the conference was a short walk from the site the centenary was about. The north face and Forbes Quarry are visible from the same stretch of road, and the Gibraltar National Museum is roughly ten minutes on foot into town.

The building has an indoor pool and a gym, and we are listed across 300+ booking channels, though booking direct at victorysuites.gi is the route where you can message the team, which matters when a delegation needs several apartments in one building.
