The site was constructed for the Second Augustan Legion, a group of 5,000 soldiers.
The Roman name for the fortress was Isca Augusta, named after the nearby River Usk.
The bath complex included a large outdoor swimming pool, the natatio, which was rare for legionary forts.
The walls were originally faced with colourful local stone and decorated with painted plaster.
The site contains the only known remains of a legionary bathhouse in the UK that is still exposed to public view.
The amphitheatre, situated nearby, could accommodate approximately 6,000 spectators.
Archaeologists uncovered thousands of items, including a curse tablet written on lead.
The hypocaust system operated by circulating hot air beneath the raised floors of the heated rooms.
Caerleon Roman Fortress Baths (Isca Augusta) represent the best-preserved remains of a Roman legionary bath complex in Britain. The site features an indoor museum housing artifacts recovered from the fortress, including ornate pottery, military equipment, and inscriptions. Visitors can view the original layout of the bathhouse, including the natatio (swimming pool), the frigidarium (cold room), and the hypocaust heating systems. The site remains physically connected to the nearby Roman amphitheatre, the most complete of its kind in the UK. Archaeologists identified the bathhouse as a major social hub for the Second Augustan Legion, who were stationed here from approximately 75 AD. The site layout demonstrates the advanced Roman engineering of water management and climate control. Visitors walk along elevated viewing platforms that provide a comprehensive perspective of the subterranean Roman architecture. Excavations have revealed extensive drainage systems and remains of the original masonry. This site is managed by Cadw, the Welsh historic environment service.
