Ancienne résidence de l'Evêque d'Accia

The Ancienne résidence de l'Évêque d'Accia is a set of ruins in Casalta, a small village in Haute-Corse, in the Ampugnani region on Corsica's eastern side of the island's interior. Classified as a historic monument on 20 February 1980, the stone remains recall a time when Casalta was the seat of one of the island's six historic bishoprics.

What will you see on site?

Visitors find modest but telling ruins of a building that once adjoined the diocese's old church, constructed and reworked between the 12th and 17th centuries. The house served the bishops of Accia as lodging during pastoral visits through their diocese — this was never meant to be a grand cathedral palace, but a practical dwelling attached to the church. Sections of wall and the outline of the original layout survive, giving a sense of the building's original scale. The site is now municipal property and stands as a physical trace of Corsica's medieval ecclesiastical structure.

How do you get there?

Casalta lies inland in the Haute-Corse department, among the hills of Ampugnani, not far from Ponte-Leccia and the road connecting the coast to the island's interior. Arriving by car is the most practical option — local roads wind through the hilly terrain typical of the region, with views over the Golo valley. The ruins sit within the village itself, right alongside the existing houses, so no long walk is needed once you arrive.

Why does this place matter historically?

The diocese of Accia was the smallest of Corsica's bishoprics, covering only two pievi — Ampugnani and Rostino. From 1133 Casalta became its seat, with the bishops placed under the jurisdiction of the archbishopric of Genoa. The diocese's fate was sealed in 1563, when Pope Pius IV merged Accia into the diocese of Mariana and left only a vicar in charge at Casalta. Because that vicar resided there only rarely, the building began to fall into disrepair, a decline completed when the site was abandoned toward the end of the 18th century. Interestingly, the title of Bishop of Accia never fully disappeared — it was revived in 1968 as an honorary title, and since 2014 has been held by an auxiliary bishop based in Goiânia, Brazil, though this bears no practical connection to Casalta today.

When should you visit?

Spring (April–June) and early autumn (September–October) are the best times to explore inland Corsica, when temperatures are mild and the maquis-and-vineyard landscapes of Ampugnani look their best. Summer can get hot, and the mountain roads see heavier traffic as coastal visitors venture inland. Winter is quiet here, though mountain weather can turn unpredictable.

Frequently asked questions

Can you go inside the ruins? The site is visible from outside as wall remains; being a protected ruin, it doesn't offer an organized indoor visit, but the grounds within the village can be freely viewed.

How is this different from a bishop's cathedral? It was never a cathedral — just a house adjoining the church, used by the bishop during periodic pastoral visits to the diocese, which explains its relatively modest scale.

Why did the diocese of Accia stop existing? In 1563 Pope Pius IV merged it into the diocese of Mariana because of its small territory and weak administrative structure; from then on only a vicar carried out pastoral duties there.

What else is worth seeing nearby? The Ampugnani region holds other remnants of medieval religious architecture, including nearby ruined chapels, which pair well with a visit focused on Corsica's ecclesiastical history.
