Ciutadella de Roses
Historic siteWalk through the walls of the Ciutadella de Roses and you cross 2,300 years of continuous history in a few hundred metres — a Greek street grid, a Roman villa, a Visigothic building and a Romanesque monastery, all still standing inside a 16th-century artillery fortress that never bothered to clear any of it away.
A fortress that swallowed a city instead of replacing it
In 1543, Holy Roman Emperor Charles V ordered a new fortress built at Roses to defend one of Catalonia’s most valuable ports against pirates and Ottoman raids. Italian military engineer Giovanni Battista Calvi designed a pentagon-shaped enclosure with angled bastions — a genuinely new kind of military architecture built specifically to survive cannon fire, which had made traditional straight medieval walls obsolete almost overnight. What makes the Ciutadella unusual is what happened next: rather than levelling the ground inside those walls, the fortress simply enclosed everything that was already there. Greek streets, Roman foundations, a medieval monastery — all of it sits inside the ramparts today, protected rather than destroyed by the very walls built centuries after them.
Four civilisations, one walled enclosure
The site’s story starts around the 4th century BC, when Greek settlers founded the trading colony of Rhode — the origin of the modern town’s name. Rome absorbed the settlement in the 2nd century BC, renaming it Rhodas and leaving behind the remains of a villa and a necropolis still visible today. After Rome’s collapse, Visigothic-era buildings appeared on the same ground, and by the 10th century a Benedictine monastery, Santa Maria de Roses, had risen here — recognised as the earliest known example of Lombard Romanesque architecture anywhere in Spain. Each layer left something behind rather than replacing what came before, and the 16th-century fortress that finally enclosed the whole site preserved that stacking rather than erasing it.
Rhode, the Greek colony
Streets, house foundations and public spaces from the 4th–3rd century BC settlement, among the earliest Greek colonies on this stretch of coast.
Santa Maria de Roses
A 10th-century Benedictine monastery church, recognised as Spain’s earliest known example of Lombard Romanesque style.
The Sea Gate
The fortress’s monumental entrance from the water, part of a 131,000 m² enclosure purpose-built to resist artillery bombardment.
A dig that never stopped
Archaeological campaigns continue at the site every year, regularly turning up new detail about daily life across every period represented here.
From war machine to cultural venue
The Ciutadella stayed a functioning military installation for roughly three centuries, surviving Napoleonic-era sieges in the 1790s and remaining under military control well into the 20th century. It was decommissioned and declared a Cultural Heritage Site in 1961, and the transformation since then has been complete: what was designed to withstand siege now hosts open-air concerts, exhibitions and an annual citadel festival, alongside the ongoing archaeological work that keeps adding to the site’s four-civilisation record.
Frequently asked questions
Why does the fortress contain ruins from so many different eras?
The 16th-century fortress was built to enclose an area that already held Greek, Roman, Visigothic and medieval remains, and rather than clearing the ground, it simply walled the whole layered site inside its ramparts.
What was Rhode?
Rhode was the Greek trading colony founded here around the 4th century BC — the origin of the modern name Roses, and the oldest layer of the site’s history.
Is the monastery still intact?
Substantial remains of Santa Maria de Roses survive, including its Romanesque church, recognised as the earliest known example of that architectural style in Spain.
Is the site still being excavated?
Yes — archaeological campaigns continue on a regular basis, and new findings are still being made across the site’s Greek, Roman and medieval layers.
