The Church of Santa Vittoria, situated in the historic centre of Aggius, is one of the most important religious buildings in Gallura, with origins dating back as far as the 14th century. According to sources held at the Bishop’s Curia, the present church was built in 1536, although over time it has undergone numerous alterations that have profoundly changed its appearance.

Completely rebuilt in the early 18th century, the church now features a neoclassical façade characterised by an elegant pediment and a large portal framed by mouldings. A string course divides the façade, at the centre of which there is a lunette window. Next to the building stands the square-plan bell tower, approximately 33 metres high, built in the 20th century along with the portico and the sacristy.

The church has a Latin cross plan with three naves, divided by sturdy pillars supporting arches and barrel vaults. The spacious and light-filled interior is enhanced by four chapels on each side, also covered by barrel vaults. At the rear is a deep semi-circular apse, built between 1745 and 1756, which houses the chancel, raised above the nave.

The structure, built of exposed granite blocks, is reinforced externally by buttresses, whilst inside natural light filters through the lunette windows above the chapels. The flooring, which was replaced during the 1968 restoration, features an elegant two-tone effect created by the alternation of light and dark marble.

Today, the church of Santa Vittoria is not only the main place of worship in Aggius, but also a significant testament to the religious and architectural history of the area, capable of recounting centuries of transformation and devotion.
