Mountain village of Ogliastra, Seui is first mentioned in documents dating back to 1300 under various spellings: “shuy”, “sechuy”, “Sheuuy”. Nuragic remains are scattered throughout the territory. Particulary interesting are the archaeological sites around Tonneri and Montarbu. The old section in the village centre, with its tortuous streets of medieval origin and its stone houses and balconies with wrought iron railings is undoubtedly an attraction for visitors. Also of interest is the museum itinerary which includes the Spanish prison, “Casa Farci”, the Art Nouveau building from 1900, and the 19th century townhall with its civic gallery. The museum houses artefacts of country life, from the world of sheep-farming, the mining civilisation and local crafts. The objects on show represent a tangible heritage of customs and local traditions.

The parish church and the country churches should not be missed either. The “laveria del carbone” (coal wash place) from the 19th century and the mining village of Fundu de Corongiu, abandoned in 1959 are also worth a visit, as both highlight important features of the history of the community.

In Seui there is one of the oldest railway stations in Sardinia. It is a narrow gauge railway , the only one of its kind still operating in the world, for this alone it is considered a living piece of industrial archaeology. To keep the Trenino verde tradition alive,  every year the Sardinian Railways organise excursions for tourists along the most characteristic and impervious stretches of railway in Sardinia.

Of remarkable interest is the natural oasis of Montarbu to be included in the forthcoming Gennargentu National Park. Limestone cliffs, breathtaking landscapes and rare flora and fauna endemisms make this territory an ideal destination for mountain tourism.

The economy of Seui is based mainly on forestation, goat-herding, iron and wood handicrafts, and the baking of sweets and bread.
