The History of Kaštilac, a Croatian Fortress Built by Nuns

Key facts

  • The fortress was commissioned by the women’s Benedictine monastery from Split to protect their tenant farmers.
  • Construction began in 1529 after a contract was signed with masons Jakov Marković, Grgur Liunić, and Pavle Zudenig.
  • The structure measures approximately 35 by 38 meters and was built on a reef 40 meters from the mainland.
  • The site is historically linked to a 1078 land grant from King Zvonimir to the Split Benedictines.

The Kaštilac fortress in central Dalmatia, Croatia, stands as a historical anomaly built by the Benedictine nuns of Split during the 16th century. Unlike many military structures of the era, the fortress was commissioned by women to provide refuge for their tenant farmers and protect their landholdings. It is situated on a sea reef in Kaštela Bay, connected to the mainland by a stone arched bridge.

Construction and Design

The fortress was built on a shallow reef approximately 40 meters from the shoreline. Its design features a rectangular ground plan, a defensive wall, and a high tower above the entrance. Historical records indicate that the structure was originally accessed by boat through sea gates on the southern wall, though a wooden drawbridge was also used before the current stone bridge was constructed. Construction began in 1529 following a contract with Trogir masons and was completed around 1545.

Historical Context

The Benedictine nuns' presence in the region dates back to 1078, when King Zvonimir granted them an estate in the Kaštela plain. By the 1520s, intense Ottoman raids necessitated defensive measures, leading to the destruction of the nearby village of Kozice around 1532. The fortress, originally known as Kaštel Opatica (Castle of the Abbess), provided shelter for sixteen families within its walls. Unlike many other fortresses, Kaštilac remains inhabited today, with houses lining its internal courtyard.
