The great Canadian explorer Guillermo Farini described in a paper a mysterious city, discovered in the Kalahari Desert in 1885.
The report was sent to the Royal Geographical Society in the United Kingdom, along with a collection of sketches and photographs, and Farini also published a book describing the findings in detail.
Farini, one of the first Westerners to cross the Kalahari Desert, claimed that the city had been built in the shape of a circular arch, and some sections were buried in the sand at the time of the discovery of the ruins.
Professor A. J. Clemente, who researched the images and history of the place, assumed that the city described in Farini's report was a simple agglomeration of natural rocks, which only resembled the walls of a human settlement.
Since the report was published, at least 25 expeditions have been organized to the Kalahari, in the area indicated by Farini, but scientists have failed to locate the walls described by the Canadian explorer.
