Castello di Terra

Castello di Terra (English: Land Castle) is a former medieval coastal fortress in the historic centre of Trapani, Sicily. In the sixteenth century it formed part of the city’s bastionised defensive system, serving as the principal landward stronghold protecting the harbour and urban core. Today, only sections of the seaward defensive walls survive, while the former landward area of the castle site is occupied by modern administrative buildings, including the Questura of Trapani, which houses the provincial headquarters of the State Police. History Castello di Terra emerged in the medieval period as a key defensive and administrative stronghold of Trapani, closely linked to the protection of the town and its harbour. The fortress served to oversee access to the port and to assert political and military authority over one of western Sicily’s principal maritime centres. Within the city’s early defensive layout, it secured the landward approach and controlled the canal linking the Tyrrhenian Sea with the harbour basin. During the sixteenth century, under Spanish rule within the Crown of Aragon, Castello di Terra was integrated into Trapani’s bastionised defence system developed in response to artillery warfare. No longer an isolated medieval fortress, the castle became the principal landward stronghold within a coordinated network of walls, bastions, and ditches protecting the city. Connected to the Mura di Tramontana and nearby works such as the Bastione dell'Impossibile, Castello di Terra formed the primary terrestrial stronghold of Trapani’s early modern fortifications, while continuing to support the city’s maritime role. Storming of the Castello di Terra In 1848, Sicily was swept by a widespread popular revolt against the Bourbon monarchy of the Kingdom of the Two Sicilies. In Trapani, local insurgents seeking political autonomy and the restoration of constitutional rights confronted royal authority, and Castello di Terra became a focal point of the uprising. An official municipal biographical reference records that the fortress was stormed by revolutionaries led by Giuseppe Coppola and Enrico Fardella. These events formed part of the Sicilian Revolution of 1848, an early episode in the broader political movements that eventually led to the unification of Italy. From the eighteenth century onward, Castello di Terra gradually lost its original military role as changes in warfare and urban defence reduced the strategic importance of the site. In later periods, the area continued to be used for institutional and military purposes, with surviving structures incorporated into barracks and administrative buildings. In the twentieth century, these earlier constructions were removed during urban redevelopment, and the inland portion of the former castle site was occupied by the modern Questura of Trapani, completed in 1990 and serving as the provincial headquarters of the State Police. As a result, Castello di Terra survives primarily through its seaward defensive remains, while the landward side reflects later phases of civic and institutional occupation. Architecture The surviving architectural remains of Castello di Terra consist mainly of sections of its seaward defensive walls, constructed in local stone and facing the historic harbour. These elements preserve the physical trace of the former fortress within Trapani’s coastal defence system and represent the only substantial portions of the original structure to have survived later redevelopment. The landward side of the site has been entirely redeveloped and is now occupied by the modern Questura di Trapani, completed in 1990 to a design by the Roman architect Riccardo Leone. The building stands on a civic piazza that also contains the Monument to the Fallen of All Wars, first erected in 1921, creating a spatial juxtaposition between surviving medieval fortifications and contemporary administrative and commemorative architecture.
