Urban castles and fortified harbours

Sforza Castle in Milan has a broad square enclosure, with cylindrical towers towards the city and square towers on the opposite side. The main façade belongs to the fifteenth-century rebuilding, while the rear preserves earlier Visconti work. Its moat is now dry, and the much larger outer defensive system was demolished. Some conspicuous medieval-looking features, including battlements, were restored in the nineteenth century.

Scaligero Castle at Sirmione occupies a narrow part of the peninsula in Lake Garda. Water-filled moats surround the castle, while a walled harbour adjoins it on the lake side. Towers, protected entrances and separate passages organise movement between the main stronghold and harbour enclosure. Both castles used moats, but Sirmione’s defences also enclosed an area of water where vessels could be sheltered behind walls.

Castel Nuovo: triumphal entrance and defensive towers

Castel Nuovo in Naples combines cylindrical towers on sloping masonry bases with the rooms of a royal palace. Its entrance is marked by a marble triumphal arch inserted between the towers. Built in the fifteenth century, the arch commemorates Alfonso V of Aragon’s entry into Naples, with reliefs presenting the ruler and his entourage through forms inspired by Roman triumphal monuments.

Beyond this ceremonial entrance are a courtyard, chapel, halls and residential elements. The building’s defensive mass and carved entrance address different purposes: the towers protected the complex, while the arch presented the legitimacy and ambitions of its royal occupant. Both remain part of the same approach into the castle.

Civic palaces and royal residences

Palazzo Vecchio in Florence has a rusticated stone exterior, projecting battlement gallery and tall tower. Defensive openings occur beneath the upper gallery, while coats of arms identify the civic authorities and political allegiances associated with the building. Inside, the Hall of the Five Hundred was created for the republican Grand Council and later transformed for the Medici rulers. Its changing decoration followed the conversion of a civic seat into a ducal residence.

The Palace of Caserta is an eighteenth-century royal complex organised on a much more regular plan. Intersecting wings divide the enormous rectangular building into four courtyards. A central passage aligns the approach through the palace with the park beyond, with separate routes for carriages and pedestrians. State apartments occupy the principal floor, while kitchens, workshops and cellars were placed below. Its structure sets out the accommodation and circulation of a large court within a unified design.

Castel Sant’Elmo: a star-shaped fortress

Castel Sant’Elmo stands on Vomero Hill above Naples. Its principal surviving form is a sixteenth-century star-shaped fortress, partly cut from the rock and built in local volcanic stone. Six projecting arms provide positions for artillery around the enclosure, with gun emplacements at the inward angles and a moat outside.

A steep ramp and defended bridge lead towards the entrance, where the imperial arms of Charles V identify the period of the main rebuilding. Further ramps connect the internal levels. This arrangement was designed around moving troops and weapons through an artillery stronghold, making it a useful counterpart to the royal halls and carved ceremonial entrance of Castel Nuovo below.
