Castello Normanno-Svevo

The Norman-Hohenstaufen Castle stands in the historic center of Sannicandro di Bari, Southern Italy, serving as a prominent medieval landmark with origins dating back to 916. Originally commissioned by the Byzantine general Niccolò Piccingli to defend Apulia against Saracen incursions, the structure began as a sturdy trapezoidal fortress featuring six towers. Over the centuries, it evolved through distinct architectural phases, blending Byzantine foundations with subsequent Norman and Hohenstaufen modifications. The castle is uniquely situated among traditional houses with external staircases and was historically surrounded by a moat that was filled in 1836 to create a modern street, yet the imposing structure remains a testament to the region's layered military history.

Significant transformations occurred under Norman rule after 1071, when Robert Guiscard restored the site, rebuilt corner towers, and added a chapel dedicated to Saint Nicholas. The most expansive development took place in 1242 under Emperor Frederick II of the Hohenstaufen dynasty, who enveloped the original core with an outer wall and massive towers to create a fortified residential palace. This era introduced specialized features such as hidden falconry spaces, reflecting the emperor's personal interests documented in his treatise on hunting with birds, along with a secret escape tunnel leading toward Bitetto. At its peak during this period, the complex boasted nine towers and grand mullioned windows within the baronial palace.

Today, the castle represents a crucial piece of Italian heritage, showcasing the strategic and architectural shifts from Byzantine defense post to imperial residence. While the text cuts off before detailing later Angevin influences, the existing structure preserves the physical evidence of these major historical epochs. It currently stands as a protected monument, offering visitors a glimpse into the feudal past of the Bari region and the specific legacy of Frederick II's centralized power. The building continues to anchor the local landscape, bridging the gap between ancient ruins and the developed township that grew around its protective walls.
