Celemantia: the biggest Roman fort in Slovakia
Celemantia (Castra Celemantia, today also called Leányvár or Dievčí hrad) was a Roman fort on the left bank of the Danube, in the municipality of Iža a few kilometres east of Komárno. It is the largest known Roman military site in present-day Slovakia and, since 2021, part of the UNESCO World Heritage site Frontiers of the Roman Empire: The Danube Limes. Today it is an open-air archaeological site for anyone interested in Roman history.
Rome built its only fort of this stretch of the frontier on the wrong side of the Danube, facing the barbarian Quadi. It burned, was rebuilt in stone and now carries a girl's name.
The history of Celemantia
In the course of the 1st century the Romans conquered Pannonia and pushed the border of their empire to the Danube. The far bank, the land of the Germanic Quadi, was the Barbaricum. Opposite the legionary camp of Brigetio, just east of the mouth of the Váh, the Romans built a bridgehead on that far bank, the fort later known as Celemantia. The name appears in the 2nd century in the geography of Claudius Ptolemy among Germanic territories, but the fort is not named in other ancient sources, and the identification rests on later research.
The first, temporary-looking camp was built in the 170s, during the Marcomannic Wars under Marcus Aurelius. It was meant to be permanent, though, not just a base for campaigns against the Quadi. Its timber palisade enclosed at least three hectares behind earth ramparts and a double ditch. Inside stood eleven barracks of mud-brick, each 44 to 48 metres long, and the weapons found suggest mounted archers. A fire destroyed this fort around 179, as the last coins show, probably in a Germanic attack, and the Romans then built several smaller earth camps nearby as bases for operations.
After the wars, under Emperor Commodus, the Romans rebuilt the fort in stone on the same site. The new fort was almost square, about 172 metres on each side and covering more than three hectares, with rounded corners and 20 towers. Its walls were 1.8 metres thick and at least 4 to 5 metres high. A gate with two towers opened in the middle of each side; the south gate faced the Danube and the link to Brigetio. Unusually, the headquarters stood near the west gate rather than at the centre. The baths lay in the south-east, a granary in the north-east, and large bread ovens and wells served the garrison. Nearly all building material had to be shipped across the river, and stamps on the bricks show that builders of the legion I Adiutrix from Brigetio took part. A wall running from the south-west tower towards the river suggests that the fort helped to protect a Danube bridge.
The stone fort was damaged in the fighting of the mid-3rd century and modernised in the 4th, when bastion-like towers were added to the north gate and three corners. Its end was probably violent, after the Quadi and Sarmatian war of 374 to 375, as the burnt layers show; English sources say the site ceased to exist around 400. The ruins stayed well visible until the late 18th century, when stone was taken to build the fortress at Komárno. Later tradition says King Béla IV gave the ruins to the Dominican nuns of Margaret Island, who built a small fortress among them. Excavations began in the early 20th century with János Tóth-Kurucz, and systematic research by the Slovak Academy of Sciences has run since 1978. The site became part of the UNESCO list in July 2021.
Curiosities about Celemantia

- It was the only Roman limes fort on this stretch of the frontier that was pushed forward onto the left bank of the Danube, facing the legionary camp of Brigetio.
- The Hungarian name Leányvár means Girl Castle. A local legend says that a Roman soldier named Valentin kept his mistresses here, but the story is fictitious. The name probably refers to King Béla IV's gift of the ruins to the Dominican nuns of Margaret Island.
- Excavations produced more than 1,500 coins, which allowed archaeologists to date the different building phases very precisely.
- A gilded disc brooch showing the god Serapis and a 3rd-century ivory figure of a comic actor were found among the finds.
- The soldiers baked bread in large communal ovens that stood away from the barracks, near the towers, probably for fire safety.
