Castello Angioino-Aragonese

The Castello Angioino-Aragonese occupies a rocky spur above Gaeta's medieval quarter. Its lower Angevin and upper Aragonese sections preserve centuries of defensive architecture and later military use, including a former prison in the Angevin wing.

Why it matters

The fortress's origins reach back to the sixth or seventh century, after the Gothic invasions. Medieval and Renaissance rulers expanded the defences, producing the two communicating sections associated with the Angevin and Aragonese periods. The complex served the state in successive military roles through the modern period.

What to notice

The lower Angevin section is associated with the reign of Charles of Anjou; the higher Aragonese section was developed to strengthen the fortress in the age of Charles V. The division between construction phases remains legible in the two-part plan. The complex preserves massive curtain walls, gun positions and thick masonry overlooking the Gulf of Gaeta and Monte Orlando.

Context and history

Gaeta's defensible promontory above a deep gulf made it a strategic position. The national tourism board traces the first castle to the sixth and seventh centuries. The fortress was expanded during the Angevin period under Charles of Anjou and during the Aragonese period, with further reinforcement under Charles V in the sixteenth century, when gunpowder changed defensive architecture. The complex covers more than 14,000 square metres and its two parts communicate. The Aragonese wing housed a Carabinieri cadet school until the end of the Second World War and later a nautical school of the Guardia di Finanza. Part of the Angevin buildings became a military prison, while other parts were assigned to university use.
