As it stood in 1539
What Castle of Charles V looked like in its prime.
A compact quadrangular fortress of pale Lecce limestone ashlar dominated by a massive square keep rising above a broad inner courtyard. Smooth, lightly weathered stone walls pierced by small rectangular windows and ground‑floor round‑arched loggias frame the paved courtyard; the main tower shows a pronounced band of corbels/machicolations beneath its flat summit. Rooflines are essentially flat with simple parapets; barrel‑vaulted recesses and heavy stone portals open from the courtyard into covered halls. Masonry is intact and clean at its prime.
Its story
The story of Castle of Charles V.
The Thirteenth-Century Core and the Orsini del Balzo
Archaeological work by the University of Salento has identified the oldest known core of the castle, of the thirteenth century and the opening of the fourteenth, between the Swabian and the Angevin age. The tall square tower that still stands at the centre of the sixteenth-century fortress belongs to that phase, and the whole later plan grew out of it. A register of 1463 appears to document at least three gates, among them the primus introitus that now opens on Piazza Libertini, probably the Porta Regale mentioned in 1544 and 1545, and a false gate beside the Torre Magistra. The Orsini del Balzo held the castle in the fourteenth century, and a story told of them has it that they kept a white bear in the moat, as much for standing as to discourage intruders.
Charles V's Order of 1539 and the New Fortress
In 1539 the emperor Charles V ordered the old princely bulwark, medieval in date, pulled down and a new fortress raised to the most advanced military architecture of the day. The work of design and construction was entrusted to Gian Giacomo dell'Acaya, engineer general of the Kingdom of Naples, though his hand in it is not held to be certain and several men versed in military architecture are known to have worked there. The outer circuit went up between 1539 and 1549. Room was made by demolishing a convent and its church of the Holy Cross, afterwards rebuilt in via Umberto I, along with a royal residence of which some trace survives inside the central block. The rear side, the most developed and the most strongly fortified, faced the danger of attack from the nearby Adriatic coast, and the castle stood on a road important since Roman and then medieval times, the way down to San Cataldo, the port of Lecce.
Theatre Hall, Barracks and the Comune of Lecce
The building's uses were not only military: in the eighteenth century one of its halls was fitted up as a theatre. In 1872 the moat that ringed it was filled in and the drawbridges of its two gates, the Porta Reale and the Porta Falsa or di Soccorso, were taken away; the second of them has since been reopened. From 1870 to 1979 the castle served as barracks and military district, and on 30 April 1983 the military administration made it over to the comune of Lecce. It is listed as Italian national heritage, and the comune keeps its department of culture there and runs it as a centre for cultural activity, the first floor given over to events and exhibitions.
