The Roman army reached Exeter around AD 50-55 during the conquest of south western Britain

Medieval Exe Bridge

On a spur overlooking the River Exe a 42 acre legionary fortress was built.

 This was the base for the 5000 strong Second Augustan Legion.


The fortress occupied a commanding position overlooking the River Exe, defended on two sides by steep valleys.

 The defences and buildings of the fortress were constructed almost entirely from timber and clay.

The one exception was the bath house which had walls of volcanic stone quarried from Rougemont Hill.

It was an impressive building and was the equivalent to the modern sports hall.

 Nothing was known of the bath-house until it was excavated by the Exeter Museums Archaeological Field Unit between 1971-76.

 It lay at a depth of up to 3m below the present surface of the Cathedral Close and was covered by Saxon and medieval cemeteries.

 Following excavation the bath-house was covered with sand so that it will be possible to re-open the site at some future date and place it on permanent display. The remains are amongst the most impressive of any Roman bath-house in Britain.


In about 75 the legion was transferred to Caerleon in South Wales and the fortress was abandoned.

 A few years later work began to convert the site into a civilian town, known as Isca Dumnoniorum.{ The waters of dumnonia not exeter }

 Its public buildings included a forum and basilica (town hall), a market place and public baths.


In about 180-200 the City Wall was built, enclosing 93 acres, a much larger area than that of the fortress and early town.

About two thirds of the City Wall remains; it has been patched and repaired over the centuries but some original Roman masonry can still be seen.

The sites of the gates were retained in the following centuries but little remains of the Roman grid street pattern.

 Only the northern part of the High Street follows the Roman lines.


Displays of Roman finds from the city can be found in the Royal Albert Memorial Museum on Queen Street.

 variously specified as Isca Augusta or Isca Silurum, was the site of a Roman legionary fortress and settlement or vicus, the remains of which lie beneath parts of the present-day suburban village of Caerleon in the north of the city of Newport in South Wales.

 The site includes Caerleon Amphitheatre and is protected by Cadw.

 Headquarters of the Legion "II Augusta", which took part in the invasion under Emperor Claudius in 43, Isca is uniquely important for the study of the conquest, pacification and colonisation of Britannia by the Roman army.

 It was one of only three permanent legionary fortresses in later Roman Britain and, unlike the other sites at Chester and York, its archaeological remains lie relatively undisturbed beneath fields and the town of Caerleon and provide a unique opportunity to study the Roman legions in Britain.

Excavations continue to unearth new discoveries, in the late 20th century a complex of very large monumental buildings outside the fortress between the River Usk and the amphitheatre was uncovered.

 This new area of the canabae was previously unknown.

The Brythonic name Isca means "water" and refers to the waters

 The suffix Augusta appears in the Ravenna Cosmography and was an honorific title taken from the legion stationed there.

The place is commonly referred to as Isca Silurum to differentiate it from Isca Dumnoniorum and because it lay in the territory of the Silures tribe. owever, there is no evidence that this form was used in Roman times. The later name, Caerleon, is derived from the Welsh for "fortress of the legion".
