From its small houses, you will have a splendid view of Lake Omodeo, one of the largest artificial lakes in Italy and a mesmerizing naturalistic attraction. When the water level in the lake drops, you can admire the remains of nuraghes and trees of a petrified forest. Tadasuni is a small village of just 150 inhabitants in the historical territory of Guilcer-Barigadu, which sits at an elevation of about 200 metres on the lake’s western bank. An interesting theory about the origins of the town’s name was proposed by the historian Spano: he thought it derived from the Semitic thet-ashàn, ‘rich home’. The town is mentioned in the condaghe of the Church of Santa Maria di Bonarcado, in an entry regarding the property of Camaldolese monks in Sardinia, who settled in the area when it was part of the Giudicato of Arborea.
