The Monolithe de Corbara — sometimes called the Monolitu d’Algaghjola in Corsican — is a giant unfinished granite column lying on a hillside above Corbara, on the Mediterranean island of Corsica. Despite its monumental appearance, it is not a prehistoric megalith. It is an 1839 industrial-era quarry block, carved on-site to support a colossal statue of Napoleon I destined for Ajaccio, the emperor’s birthplace. The stone proved impossible to transport off the hillside on which it was hewn, and it has lain there, unfinished and uninstalled, for nearly two centuries.

Dimensions and Weight
The monolith measures roughly 17.36 metres long and 2.74 metres in diameter, with an estimated weight of around 272 tonnes. It is cut from a particularly pure form of local granite known as “Algajola granite”, the same building stone that supplied the columns of the Medici Chapel in Florence and the base of the Vendôme Column in Paris.
Why was the Monolithe de Corbara carved?
In 1839, plans were drawn up in Ajaccio to erect a monumental statue of Napoleon I, who had been born in the town in 1769. The Corbara quarry on the north-west coast was selected as the source for the colossal base on which the statue would stand. Quarrymen cut the entire column on-site from the parent rock, intending to roll and slide it down to the coast for shipment to Ajaccio. The plan collapsed under the column’s own weight: no available technology of the time could move 272 tonnes of granite across Corsica’s interior terrain, and the project was abandoned. The monolith was left where it was carved and has remained there ever since.
The Monolith Today
The Monolithe de Corbara remains on its original site, on privately owned land on the slopes above the village. It carries no formal historic-monument protection but is well known locally and has become a minor tourist attraction in the Balagne region. It is a striking reminder that the imperial ambitions of nineteenth-century Europe could be defeated by ordinary geology — a 272-tonne column carved with extraordinary skill, but never moved.
