tribe, the largest and most northerly tribe in Roman Britain. Roman towns such as Exeter, Leicester, Chichester and Canterbury had the same status as ''Isurium''.
Tacitus recorded that ''Isuer'' was the seat of
Venutius, king of the Brigantes who was usurped from power by his wife,
Cartismandua
Cartimandua or Cartismandua (reigned ) was a 1st-century queen of the Brigantes, a Celtic people living in what is now northern England. She came to power around the time of the Roman conquest of Britain, and formed a large tribal agglomeration t ...
and her lover Volucatus at the beginning of the first century. Cartismandua welcomed the Romans who perceived little threat from the Brigantes and the Roman army focused its occupation to the south of Brigantium. When Venutius and his followers began to attack Brigantian centres towards the end of the first century, the Roman army pushed further north. Tacitus reports the final subjugation of the Brigantes came about by
Julius Agricola in 79 AD. who then constructed Isurium.

Its name is believed to be derived from the Latin name of the river ''Iseur'' now the
River Ure. It is likely there was a Brigantian settlement at ''Isurium'' before the Roman invasion. There are many prehistoric sites along the

It was supposed that Isurium was the site of a 1st-century
Roman fort

Boroughbridge and 1st-century finds at Aldborough most likely come from a related civilian site. Isurium Brigantum had substantial buildings from an early period; probably by the early 2nd century. Bank and ditch defences were erected later. Stone walls and four gates were added in the mid-3rd century. The visible remains are a small fraction of the Roman town. Isurium flourished for the next hundred years, with the building of elaborate private homes with fine decorative
mosaic floors. In the middle of the 4th century,

The 16th-century antiquary
John Leland noted, ''"There be now large feeldes, fruteful of corn, in the very places where the howsing of the town was; and in these feeldes yereley be founde in ploughing many coynes of sylver and brasse of the Romaine stampe—Ther also have been found sepulchres, aqaue ductus tessalata paviamenta &.c.''"

Daniel Defoe (; born Daniel Foe; – 24 April 1731) was an English writer, trader, journalist, pamphleteer and spy. He is most famous for his novel ''Robinson Crusoe'', published in 1719, which is claimed to be second only to the Bible in its ...
wrote ''"Not so much ruins, especially not above ground"''.
In 2011, geomagnetic scanning revealed the existence of an
amphitheatre, emphasising Isurium's importance as a major Roman town.
The site came to prominence during excavations taking place in 2004. A young archaeologist, Daniel Ebdon, was using a metal detector for the first time and uncovered a Roman coin. This, along with others of its kind, can be found in The Yorkshire Museum, York.
Aldborough Roman Site
Aldborough Roman Site is in the care of
English Heritage and consists of a stretch of the massive town wall with its defensive towers and two in-situ mosaic pavements, once part of a Roman townhouse. A display of archaeological finds from the site are on display in the museum providing an insight into the lives of Roman civilians in its most northern capital.
