Lindum Colonia was a Roman town and which is now modern-day Lincoln in England. The Roman town was originally founded as a Roman Legionary Fortress during the reign of Emperor Nero. The town is thought to have been founded sometime in 80 AD and abandoned in the 5th century.
Sections of the original Roman wall that surrounded and protected the settlement remain in different places in the East Bailgate part of Lincoln. Two granite circles on a pavement mark the location of two buried Roman columns. The Newport Arch is the oldest arch in the UK to still be used by traffic also remains from the Roman settlement. The northern tower of the eastern gate also remains.
