Segedunum was a Roman fort at modern-day Wallsend, North Tyneside in North East England. The fort lay at the eastern end of Hadrian's Wall near the banks of the River Tyne. It was in use for approximately 300 years from around 122 AD to almost 400. Today Segedunum is the most thoroughly excavated fort along Hadrian's Wall, and is operated as Segedunum Roman Fort, Baths and Museum. It forms part of the Hadrian's Wall UNESCO World Heritage Site.
Five places named Segedunum are known to have existed in the Roman empire, one each in Britain and Germany and three in Gaul.
The name Segedunum is known from the Notitia Dignitatum of the 4th century, but there is no consensus on its meaning. The various conjectures include "derived from the Celtic for 'powerful' or 'victorious'", "derived from the [Celtic] words sego ('strength') and dunum ('fortified place')", "Romano-British Segedunum 'Strong-fort'", and "Celtic sechdun or 'dry hill'".
The first element of the name is attested widely in Gaul, Spain, Germany and Italy, and derives from the Indo-European root segh-, which is reflected in various later European languages with similar meanings: Irish seg-, segh- 'strength, vigour', Welsh hy 'daring, bold', German Sieg 'victory', and so on. As applied to place names, it appears to have had the meaning of "place of strength" or "place of victory". The second element, -dunum, is a Celtic term widely attested across Britain and Gaul and typically meant a fort. Thus Segedunum probably had the meaning of "strong fort" or "victory fort".
The Roman wall originally terminated at the fort of Pons Aelius (Newcastle upon Tyne) begun in 122 AD. Subsequently, in about 127 AD, the wall was extended further east by 4 mi (6 km), possibly to protect the river crossing at Pons Aelius, passing through present-day Byker to the new fort of Segedunum. The new section of wall was narrower than those previously built, being 7 feet 6 inches (2.29 m) wide on a foundation of 8 feet (2.4 m). Unlike the rest of the wall, the extension had no Vallum ditch and embankment on the south side. It was probably not needed here because its role was performed by the River Tyne.
The fort of Segedunum measured 453 feet (138 m) from north to south and 393 feet (120 m) from east to west, covering an area of 4.1 acres (17,000 m2). A wide ditch and an earth embankment surrounded the fort on all sides. It had four double gates with the east, west and north gates opening outside the wall and only the south gate opening within the wall. The wall joined to the west wall of the fort just south of the west gate. From the southeast angle of the fort, a 6 feet 6 inches (2 m) wide wall ran down to the riverbank and extended at least as far as the low water level.
