Castiadas and the Sarrabus Region
The Historical Region of Sarrabus
Sarrabus is located in southeastern Sardinia between the Sette Fratelli mountains and the
Tyrrhenian Sea. Characterized by forested valleys, agricultural plains, and coastal wetlands, the
area forms part of the historical Sarrabus-Gerrei district.
Overview of Castiadas
Castiadas is a dispersed agricultural and coastal municipality in the Sarrabus region, composed of
a central administrative area (Castiadas Centrale) and multiple historical agricultural villages (Olia
Speciosa, San Pietro, Camisa, L’Annunziata). Its economy is rooted in citrus and grain farming,
viticulture, sheep herding, and high-end coastal tourism.
Origins & History:
While the territory contains ancient Nuragic nuraghi and Giants’ Tombs,
modern Castiadas owes its existence to a major 19th-century penal colonization and land
reclamation project. On August 11, 1875, thirty convicts and seven guards from Cagliari’s San
Bartolomeo prison landed at Cala Sinzias to clear malaria-infested marshes and establish the
Castiadas Penal Colony. Operating until 1953, the convict labor force constructed roads,
administrative buildings, and agricultural outposts that transformed the marshy plain into a
productive farming district. In 1986, Castiadas was formally constituted as an independent
municipality by combining parts of Muravera, San Vito, and Villaputzu.
Key Sites & Cultural Highlights
• Former Castiadas Penal Colony & Territorian Museum: Built in 1877 as a penal facility,
the restored stone director’s wing and cell blocks now house the Museo del Territorio,
documenting the harrowing history of the prison and the grueling land-reclamation labor.
• Church of San Basilide: A late-19th-century rural chapel situated within the San Basilide
park, dedicated to the patron saint of the prison police corps.
• Church of San Giovanni Battista (Olia Speciosa): A modern parish church consecrated in
1960 within the administrative hamlet of Olia Speciosa.
• Castiadas Coastline & Beaches: A stretch of pristine southeastern coastline featuring
scenic coves and expansive white-sand beaches:
◦ Cala Pira: A small cove backed by granite cliffs and Mediterranean scrub, overlooked
by the 1739 Spanish watchtower (Torre di Cala Pira).
◦ Cala Sinzias: A long, golden-sand beach framed by rocky promontories, pine woods,
and sand dunes (noted for hosting endangered loggerhead sea turtle nesting sites in
recent years).
◦ Cala della Marina (San Pietro) & Santa Giusta: Fined-grained white sand beaches
backed by low dunes and tourist infrastructure.
◦ Costa Rei (Scoglio di Peppino): A sweeping coastal resort area featuring the iconic
Scoglio di Peppino, a giant grey granite rock resting at the water’s edge.
• S’Omu e S’Orcu Nuraghe: Located near Santa Giusta, this is the largest complex nuraghe
in southeastern Sardinia, featuring a central keep surrounded by five auxiliary bastions, a
courtyard, and the traces of an associated Nuragic village.
