Porto Flavia is a sea harbour located on the coast of Nebida in southwestern Sardinia. It was opened in 1924 and at that time it was a true revolution: a modern tunnel system for transporting minerals from Masua and nearby mines directly into the ships moored under the cliff, reducing the time and cost of transportation. It is named after Flavia Vecelli, the daughter of Cesare Vecelli, who engineered and designed the harbour. Its unique architecture, combined with the beautiful blue waters, white cliffs perfect for climbing and the view of Europe's tallest sea stack, called Sugar Loaf, creates a picturesque and memorable scenery that you absolutely must visit.
