Saint Albans () is a cathedral city in Hertfordshire, England, east of Hemel Hempstead and west of Hatfield, north-west of London, south-west of Welwyn Garden City and south-east of Luton. St Albans was the first major town on the old Roman road of Watling Street for travellers heading north and became the city of Verulamium. It is within the London commuter belt and the Greater London Built-up Area. Name St Albans takes its name from the first British saint, Alban. The most elaborate version of his story, Bede's Ecclesiastical History of the English People, relates that he lived in Verulamium, sometime during the 3rd or 4th century, when Christians were suffering persecution. Alban met a Christian priest fleeing from his persecutors and sheltered him in his house, where he became so impressed with the priest's piety that he converted to Christianity. When the authorities searched Alban's house, he put on the priest's cloak and presented himself in place of his guest. Consequently, he was sentenced to endure the punishments that were to be inflicted upon the priest, unless he renounced Christianity. Alban refused and was taken for execution. In later legends, his head rolled downhill after execution and a well sprang up where it stopped. History Iron Age There was an Iron Age settlement known as, Verlamion, or Verlamio, near the site of the present city, the centre of Tasciovanus' power and a major centre of the Catuvellauni from about 20 BC until shortly after the Roman invasion of AD 43. The name "Verlamion" is Celtic, meaning "settlement over or by the marsh". The town was on Prae Hill, to the west of modern St Albans, now covered by the village of St Michael's, Verulamium Park and the Gorhambury Estate. Although excavations done in 1996 produced finds which include silver coins from the Roman Republic era dating from 90/80 BC. There was evidence of trade with the republic and that a settlement already existed on the site 50 years before Julius Caesar attempted to invade Britain. However, it is believed that the tribal capital was moved to the site by Tasciovanus (around 25 to 5 BC). Cunobelinus may have constructed Beech Bottom Dyke, a defensive earthwork near the settlement whose significance is uncertain. Roman The Roman city of Verulamium, the second-largest town in Roman Britain after Londinium, developed from the Iron Age settlement and was granted the rank of municipium
