During the period known as sub-Roman Britain (mainly in the early-mid 5th century) after the Romans left but before the Germanic tribes arrived, the ''Historia Brittonum'' (attributed to the 9th-century Welsh monk [[Nennius]]) states that there were 28 cities of Britain, all of which are named with the word ''cair'' (the precursor to the modern Welsh word ''caer'' meaning "fort", especially a former Roman one, seen in place names such as [[Cardiff]], Caernarfon, etc). Among the 28 is ''Cair Guiragon'', which is almost certainly identifiable with Worcester. In modern Welsh, the city is known as ''Caerwrangon''. | During the period known as sub-Roman Britain (mainly in the early-mid 5th century) after the Romans left but before the Germanic tribes arrived, the ''Historia Brittonum'' (attributed to the 9th-century Welsh monk [[Nennius]]) states that there were 28 cities of Britain, all of which are named with the word ''cair'' (the precursor to the modern Welsh word ''caer'' meaning "fort", especially a former Roman one, seen in place names such as [[Cardiff]], Caernarfon, etc).
