It is located in the immediate outskirts of Ghilarza, near an Aragonese tower and the rustic church of San Giorgio, along the road that leads to one of the most famous medieval religious monuments on the Island, San Pietro di Zuri. The ancient church of San Palmerio is charming and fits harmoniously into the surrounding landscape. It is halfway between urban and rural and is typical of numerous Sardinian Romanesque monuments.
The layout of the building dates back to the first quarter of the 13th century and is mentioned in the condaghe of St Maria of Bonarcado as a place in which hearings were held to settle local controversies. Originally, it had a single nave, with a wooden roof and a bell gable above the façade. The addition of a transept and a quadrangular presbytery in the 17th century meant the loss of the original semi-circular apse.
The façade is streamlined thanks to two lesenes that rise up at the sides of the portal and also to pillars that divide it into three sections, above which there are rounded arches. The central section is pierced by a cross-shaped light, while the portal has a lunette with a raised centring and an architrave that rests on monolithic jambs. Bases and capitals are decorated, but the thing that best characterises the church is its two-toned appearance, obtained by alternating dark basalt ashlars and others made from reddish vulcanite. They are arranged in rows, which alleviates the vertical effect of the façade. On the sides, you will notice single-light windows and, in the higher part, little arches set on suspended capitals, which resemble the Gothic style. The church is closed by an apsidal pediment.
The whole of the Ghilarza territory is rich in archaeological evidence, especially of the Nuragic age. When in the village, don't miss out on a visit to the Casa Gramsci museum, which revisits the fundamental stages of the life of one of the most influential twentieth century ideologists.
