Sefar, often referred to as the “City of the Giants,” is one of the world’s most mysterious and least-explored archaeological sites, hidden deep within the Tassili n’Ajjer National Park in southeastern Algeria. It is one of the largest rock art sites in the world, boasting over 15,000 ancient paintings and engravings that date back thousands of years, making it a treasure trove for historians, archaeologists, and adventurers alike.

A Glimpse into Prehistoric Times
Sefar is located in a remote region of the Sahara Desert, characterized by its surreal landscape of eroded sandstone formations, towering cliffs, and vast plateaus. The site is famous for its extensive collection of prehistoric rock art that dates back to at least 10,000 BCE. These paintings depict a wide range of subjects, including human figures, animals, hunting scenes, and mysterious beings that some interpret as mythological or even extraterrestrial.
The artwork at Sefar is grouped into several styles, reflecting different periods and cultures that inhabited the region over thousands of years. The earliest paintings, known as the “Round Head Period,” are characterized by large, elongated figures with round heads, some of which appear to be floating or in a trance-like state. Later periods show more naturalistic depictions of animals like cattle, giraffes, and elephants, indicating a time when the Sahara was a much greener and more hospitable environment.
The Myth of the “City of Giants”

Sefar’s nickname, the “City of the Giants,” comes from the towering rock formations that resemble an ancient, ruined city, complete with what look like streets, walls, and buildings. Local Tuareg legends speak of a lost civilization that once inhabited this area, often described as giants who lived in harmony with nature and possessed advanced knowledge and abilities. These stories have fueled speculation and mystery around Sefar, adding to its enigmatic allure.
Some visitors have reported feeling a strange energy or presence at Sefar, and the site has been the subject of numerous theories ranging from the plausible to the fantastical. Some believe the site has links to lost civilizations or even extraterrestrial visitors, pointing to the unusual style of some of the rock art figures as evidence. However, no concrete evidence supports these claims, and the mysteries of Sefar remain open to interpretation.
A Difficult Destination to Reach

Reaching Sefar is no easy task, which adds to its aura of mystery and intrigue. Located in one of the most remote parts of the Algerian Sahara, getting there requires careful planning, a reliable guide, and a willingness to endure harsh desert conditions. The journey involves crossing vast expanses of sand dunes and rocky terrain, often under extreme temperatures. Due to its isolation and challenging access, only a few hundred people have visited Sefar, preserving its untouched and enigmatic atmosphere.
A Unique Cultural and Historical Treasure

Despite the difficulties in accessing Sefar, the site is an invaluable cultural and historical treasure that offers a unique glimpse into prehistoric life in North Africa. The rock art provides important clues about the people who once lived in this region, their beliefs, and their relationship with the natural world. For those who make the effort to visit, Sefar offers a journey back in time, a chance to stand before some of the earliest expressions of human creativity and spirituality.
Conservation Challenges
Given its remote location, Sefar is relatively well-preserved compared to other archaeological sites. However, it still faces threats from natural erosion and, potentially, from increased tourism in the future. Efforts are underway to study and document the site more comprehensively, but the challenges of preservation in such a harsh environment remain significant.
A Place of Mystery and Wonder

Sefar stands as a testament to humanity’s ancient past, its mysteries still largely untold. Whether you are fascinated by history, intrigued by tales of lost civilizations, or simply drawn to the raw beauty of the Sahara, Sefar offers a unique and compelling destination. Its blend of natural wonder and ancient mystery makes it one of the most enigmatic sites in Algeria and indeed the world. For the intrepid traveler and the curious explorer, Sefar is a place where imagination and reality intertwine, and where the secrets of the past may yet be uncovered.
The Legend of Aleister Crowley at Sefar: The Occultist’s Mysterious Journey

Aleister Crowley, often referred to as “The Great Beast” and one of the most enigmatic figures in the history of occultism, is said to have visited Sefar, the mysterious “City of Giants” hidden deep in the Algerian Sahara. The story of his visit to Sefar is shrouded in mystery, blending elements of reality with legend, and has become a fascinating tale among those intrigued by the esoteric and unknown.
The Journey to Sefar: A Quest for Hidden Knowledge
In the early 1900s, during one of his many expeditions across North Africa, Aleister Crowley heard rumors of an ancient, remote city in the heart of the Sahara known as Sefar. This city was reputed to be home to powerful energies, forgotten knowledge, and perhaps even supernatural entities. Intrigued by these tales, Crowley, driven by his insatiable curiosity and a desire to test the limits of his magical powers, decided to make the perilous journey to this mystical site.
Crowley believed that Sefar, with its ancient rock art and mysterious atmosphere, held the keys to unlocking deeper layers of consciousness and understanding the hidden dimensions of reality. He envisioned the trip not only as an adventure into the physical unknown but also as an exploration of the spiritual and mystical realms.
The Mysterious Arrival in Sefar
Reaching Sefar was no easy task. According to the legend, Crowley traveled by camel caravan across the harsh, unforgiving landscape of the Sahara, enduring sandstorms, extreme heat, and the treacherous terrain. Accompanied by a small group of local guides, Crowley finally arrived at the site — a vast expanse of towering sandstone formations, labyrinthine caves, and ancient rock art dating back thousands of years.
From the moment Crowley set foot in Sefar, he felt a strange energy in the air. The towering rock formations, which resembled ancient ruins, seemed to whisper secrets of a forgotten time. He immediately began a series of intense magical rituals and meditative practices, hoping to make contact with whatever supernatural forces were believed to dwell there.
The Disappearance of the Caravan

As the days passed, strange occurrences began to happen. Local legends say that members of Crowley’s caravan started experiencing bizarre visions and inexplicable sensations. The guides, already wary of the city’s haunted reputation, became increasingly agitated and fearful. They reported hearing disembodied voices, seeing shadowy figures moving among the rocks, and feeling an oppressive presence that seemed to grow stronger with each passing day.
One by one, the guides abandoned Crowley, convinced that the site was cursed and that the spirits of the ancients were displeased with their presence. The last guide reportedly fled in terror, leaving Crowley alone in the City of Giants.
Crowley’s Rituals and the Final Night
Undeterred by the desertion of his companions, Crowley continued his rituals. He spent days exploring the caves and rock art, chanting incantations and performing magical rites to invoke the spiritual entities he believed resided in the area. It is said that on the final night of his stay, he performed a particularly dangerous ritual, intending to summon a powerful spirit or “djinn” to gain its knowledge and power.
According to the tale, as Crowley chanted and meditated under the light of a full moon, the wind picked up, and a fierce sandstorm suddenly engulfed the area. Visibility became almost zero, and the air was filled with an eerie, unnatural howling. Despite the terrifying conditions, Crowley remained seated, deep in trance, communicating with forces beyond the veil of reality.
The Sole Survivor Returns
When the storm subsided, Crowley was found alone, sitting calmly among the rocks, as if nothing had happened. The locals who came to check on him were shocked; they had expected to find him dead or lost to the desert. Instead, Crowley emerged unharmed, with a strange, serene expression on his face.
He never fully explained what had occurred that night, but he did allude to an intense and profound spiritual experience, claiming that he had made contact with entities who revealed powerful secrets and knowledge to him. He also hinted that he had been granted some form of protection by the spirits of the place, which allowed him to survive the ordeal.
When he finally returned to civilization, Crowley was said to be changed — more introspective, perhaps even more enigmatic than before. He carried with him new insights that he would later weave into his writings and teachings. Crowley never disclosed the full details of his experience at Sefar, leaving many to wonder what truly happened in the City of Giants.
The Mystery Remains
To this day, the legend of Aleister Crowley’s visit to Sefar remains a captivating mystery. Some believe he encountered something genuinely supernatural — ancient entities or djinns that shared forbidden knowledge with him. Others think it was a test of his psychological and spiritual endurance, a place where his inner demons manifested amidst the isolation of the Sahara.
No definitive record of Crowley’s visit to Sefar exists, and much of the story is likely embellished or apocryphal. However, the tale of his adventure in Algeria continues to intrigue those who are fascinated by the unknown, the mystical, and the esoteric, adding yet another layer to the mystique of both Sefar and Aleister Crowley himself.
