Quick Summary: Maria Reiche was a German-born mathematician who arrived in Peru in 1932 as a governess and spent the next five decades documenting and protecting the Nazca Lines, largely alone and largely at her own expense. She swept the geoglyphs clear by hand, mapped them on foot, funded guards from her book royalties, and fought for the legal protection that came in 1978 and the UNESCO listing that followed. Without her, it is entirely plausible the lines would have been crossed by roads and farmland before anyone decided they mattered.
There is a version of the Nazca Lines story that treats them as a mystery that was simply discovered — spotted from the air, declared remarkable, protected. That version leaves out the fifty years of one person’s life that sit between “noticed” and “protected.”
Maria Reiche is why there is something left to fly over. This is her story, and where you can still see traces of it in Nazca today.
Maria Reiche Grosse-Neumann was born in Dresden on 15 May 1903. She studied mathematics, physics and geography at the Technical University of Dresden, graduating in 1928 — a serious scientific training that turns out to matter a great deal later.
In 1932, aged 29, she travelled to Peru to work as a governess for the children of the German consul in Cusco. She briefly returned to Germany in 1936, then came back to Peru the following year and stayed. She worked as a private tutor and technical translator, and later as a translator and conservator at the archaeological museum in Lima, taking on multiple jobs to make ends meet.
It was through translation work that her life changed direction. Working in a café, she met the American historian Paul Kosok, and agreed to translate his English paper on the Nazca Lines into Spanish.
In 1941, Kosok took Reiche out to see the lines near the small town of Nazca.
The moment that is usually told: on the evening of 22 June 1941, Kosok was standing near one of the long straight lines when he noticed it pointed directly at the setting sun, and surmised it marked the winter solstice. Six months later, Reiche observed another line aligned with the summer solstice.
From this came their theory that the lines functioned as a vast astronomical calendar. Later scholarship has not sustained that interpretation — the astronomical reading is no longer the prevailing explanation — but the work that followed from it brought serious scholarly attention to a site that had almost none. Our guide to the main theories about the Nazca Lines covers how thinking has shifted since.
Being wrong about the purpose did not make the documentation less valuable. In some ways it is the point: she recorded the lines meticulously regardless of which theory was winning.
From 1946 she began living out in the desert for weeks at a time, and what followed is the part that earns the phrase “saved the lines.”
She measured and mapped on foot. Working across the pampas, often poorly fed, living for long stretches in a room in a farm worker’s house without running water or electricity on the edge of the desert. At night, mice ate her notes.
She swept. For years she cleared rubble and debris from the lines with an ordinary household broom so the geoglyphs would remain visible. She went through so many brooms that there were local rumours she was a witch — a detail she found funny, and which has since become the most-repeated fact about her.
She flew. The Peruvian Air Force’s aerial photography service let her fly with them, and on occasion she was strapped to the skids of a helicopter so she could hold a camera vertically over the pampa. She also worked from ladders, climbing to get enough height to recognise the shapes the lines formed.
She paid for protection. With the proceeds from her books and the support of her companion Amy Meredith, she financed guards for the site. Later, with her sister Renate and other supporters, she funded the construction of the observation tower on the Pan-American Highway — the roadside mirador travelers still climb today, gifted in 1976. Its purpose was specifically to let people see the lines without walking on them.
She defended them physically. She chased off intruders and vehicles, armed with little more than her broom, and continued doing so into old age from a wheelchair.
The campaigning mattered as much as the fieldwork, and it worked.
Peru recognised her extensively: honorary doctorates from the National University of San Marcos and the Universidad Nacional de Ingeniería, the Order of the Sun in 1993, Peruvian citizenship in 1994, and free board at a hotel in Nazca in her retirement. Schools, roads, a park and the Nazca airport carry her name.
Locals in Nazca had initially thought she was eccentric at best. Over time, as the lines brought visitors and income to the town, that view reversed completely.

Maria Reiche died of cancer on 8 June 1998, aged 95, in Lima. She is buried near the lines she spent her life protecting, and Nazca still marks the anniversary with a mass and a pilgrimage to her mausoleum.
Her daughter-in-spirit and successor in the work, Ana María Cogorno, took on the presidency of the Maria Reiche Association. Her former home in the desert became the Museo Maria Reiche, preserving her survey instruments, her notes, her VW microbus and the rooms where she worked.
You can see quite a lot of her, if you know where to look.
Our existing profile of Maria Reiche covers more of her early life, and our guides to what to do in Nazca and things to do in Nazca in one day cover how to fit these into a visit.
This is not sentiment. It is the practical frame that makes a 30-minute flight mean something.
When you fly over the pampa, you are looking at figures that survived because a woman with a broom decided they were worth saving before anyone official agreed. The lines are shallow — surface disturbance, not carving — and extraordinarily fragile. A single vehicle driven across the pampa causes damage that lasts, which is why access is restricted and why the aerial view and authorised viewpoints exist at all.
That fragility is also why the flight is short, why it departs in the early morning when visibility is best, and why you look rather than land. Knowing Reiche’s story turns the rules from an inconvenience into something closer to an inheritance.
If you want the flight side of a Nazca visit arranged so the morning runs to a plan rather than a scramble, Nazca Lines Tour handles the timing and transfers.
Why is Maria Reiche called the Lady of the Lines?
The nickname came from her near-total identification with the Nazca geoglyphs over five decades of work. She lived beside the pampa, often in very basic conditions, and spent her days measuring, mapping, photographing, illustrating and physically cleaning the lines — then spent her evenings campaigning for their protection. She was widely regarded as the curator of the site in practice long before any institution held that role formally, and she defended it personally against intruders and vehicles. By the time Peru honoured her with citizenship and the Order of the Sun, the association between the woman and the geoglyphs was complete.
Was Maria Reiche’s astronomical theory correct?
No, and it is worth being straightforward about that. She and Paul Kosok proposed that the lines functioned as a vast astronomical calendar, based on observing lines that appeared to align with the winter and summer solstices. Later scholarship concluded the lines were not chiefly astronomical, and current interpretations lean toward ritual pathways connected to water, fertility and ceremonial movement. What survived the theory’s decline was the work itself: her measurements, maps and photographs brought sustained scholarly attention to a site that had almost none, and that attention is what ultimately secured protection.
Did she really clean the Nazca Lines with a broom?
Yes, and it is more significant than it sounds as an anecdote. The geoglyphs were made by removing surface stones to expose lighter ground beneath, so they are shallow and easily obscured by drifting debris. Reiche spent years sweeping them clear by hand so they would remain visible for study and documentation, going through so many brooms that local rumour held she must be a witch. The same physical fragility that made sweeping necessary is why vehicles and foot traffic on the pampa cause lasting damage, and why access is restricted today.
How did she get the Nazca Lines protected?
Through documentation, publication and sustained pressure across decades. She financed site guards from her book royalties and, with her sister Renate and other supporters, funded the observation tower on the Pan-American Highway so people could view the geoglyphs without walking on them. After a long campaign she succeeded in 1978 in having the area placed under Peruvian government protection with access restricted. UNESCO inscription as a World Heritage Site followed in 1994, building directly on the record she had spent fifty years assembling.
Where can I see things connected to Maria Reiche in Nazca?
Several places, and they fit easily into a normal visit. Her former desert home is now the Casa-Museo Maria Reiche, preserving her survey instruments, notes, artefacts and personal effects. The roadside observation tower on the Panamericana, which she helped fund, is still the main ground-level viewpoint for the geoglyphs. The airport that flights depart from, about 3.5 km from central Nazca, carries her name. Her grave lies near the pampa, and the town still marks the anniversary of her death each June with a mass and a pilgrimage to her mausoleum.
Dates and details in Maria Reiche’s biography are recorded slightly differently across sources — the UNESCO inscription of the Nazca geoglyphs is variously given as 1994 or 1995, and accounts of her arrival, early employment and the funding of the observation tower differ in detail. Figures and dates here reflect the most commonly documented versions. Opening hours, entry arrangements and current condition of the Casa-Museo Maria Reiche, the observation tower and other sites associated with her can change, and are worth confirming locally before travelling. Scholarly interpretation of the purpose of the Nazca Lines continues to develop, so any account of what they were for reflects current thinking rather than settled fact.
