Sardinia's Ogliastra region has the world's highest concentration of male centenarians — and the local cannonau wine has 2–3x the antioxidants of typical reds. The island is one of the world's five Blue Zones, places where people live measurably longer, and its Nuragic civilisation left behind around 7,000 mysterious stone towers found nowhere else on Earth. This quiz takes you deep into the island's ancient history, unique language, stunning landscapes, and extraordinary food culture.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore nuraghi and the Nuragic civilisation, the Su Nuraxi UNESCO site, the Sardinian language and its dialects, the Costa Smeralda and Aga Khan, Blue Zone longevity research, traditional foods from pane carasau to bottarga, cannonau wine, the Giants of Mont'e Prama, Mamuthones carnival, and Sardinia's unique political status within Italy.
Sardinians speak Italian as the official language, but many also speak Sardinian (Sardo or Limba Sarda), a distinct Romance language considered by linguists to be the closest surviving language to Vulgar Latin. It has four main dialects: Logudorese, Campidanese, Gallurese, and Sassarese. The coastal town of Alghero also preserves a Catalan dialect.
A nuraghe (plural nuraghi) is a type of ancient stone tower built by the Nuragic civilisation in Sardinia between approximately 1800 and 238 BCE. Shaped like a truncated cone, the largest examples stand up to 30 metres tall. Around 7,000 nuraghi survive across Sardinia, a density of prehistoric monuments found nowhere else in the world.
Sardinia's Ogliastra and Nuoro provinces have been identified as a Blue Zone — one of five regions in the world with the highest concentration of centenarians. Researchers attribute Sardinian longevity to a combination of factors including a Mediterranean diet rich in local foods like pane carasau, pecorino, legumes, and cannonau wine, strong family and social bonds, regular physical activity (particularly pastoral walking), and genetic factors in the island's relatively isolated population.
