St Albans, United Kingdom

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 around AD 50, meaning that its citizens had what were known as "Latin Rights", a lesser citizenship status than a colonia possessed. It grew to a significant town, and as such received the attentions of Boudica of the Iceni in 61, when Verulamium was sacked and burnt on her orders. Excavations preceding the museum's new entrance done in 1996–97 within the centre of the Roman town gave archaeologists the chance to date a black ash layer to 60–65 AD, thus confirming the Roman written record. It grew steadily; by the early 3rd century, it covered an area of about 125 acres (51 ha), behind a deep ditch and wall. Verulamium contained a forum, basilica and a theatre, much of which were damaged during two fires, one in 155 and the other in around 250. These were repaired and continued in use in the 4th century. The theatre was disused by the end of the 4th century. One of the few extant Roman inscriptions in Britain is found on the remnants of the forum (see Verulamium Forum inscription). The town was rebuilt in stone rather than timber at least twice over the next 150 years. Roman occupation ended between 400 and 450 AD.

The body of St Alban was probably buried outside the city walls in a Roman cemetery near the present cathedral. His hillside grave became a place of pilgrimage. Recent investigation has uncovered a basilica there, indicating the oldest continuous site of Christian worship in Great Britain. In 429 Germanus of Auxerre visited the church and subsequently promoted the cult of St Alban.

A few traces of the Roman city remain visible, such as parts of the city walls, a hypocaust – still in situ under a mosaic floor, and the theatre, which is on land belonging to the Earl of Verulam, as well as items in the museum. Further remains beneath nearby agricultural land have only had a few exploratory trenches, which have never been fully excavated and were seriously threatened by deep ploughing, which ceased in 2005 after compensation was agreed. Test trenches in 2003 confirmed that serious damage had occurred to buildings on the northern side of Old Watling Street by deep ploughing. Permission needs to be granted to enable the full extent of the damage to the western half of Verulamium to be investigated.

After the Roman withdrawal the town became the centre of the territory or regio of the Anglo-Saxon Waeclingas tribe.

St Albans Abbey and the associated Anglo-Saxon settlement were founded on the hill outside the Roman city where it was believed St Alban was buried. An archaeological excavation in 1978, directed by Martin Biddle, failed to find Roman remains on the site of the medieval chapter house. As late as the eighth century the Saxon inhabitants of St Albans nearby were aware of their ancient neighbour, which they knew alternatively as Verulamacæstir or, under what H. R. Loyn terms "their own hybrid", Vaeclingscæstir, "the fortress of the followers of Wæcla", possibly a pocket of British-speakers remaining separate in an increasingly Saxonised area.

The medieval town grew on the hill to the east of Wæclingacaester where the Benedictine Abbey of St Albans was founded by Ulsinus in 793. There is some evidence that the original site was higher up the hill than the present building, which was begun in 1077. St Albans Abbey was the principal medieval abbey in England. The scribe Matthew Vickers lived there and the first draft of Magna Carta was drawn up there. It became a parish church after the dissolution of the Benedictine abbey in 1539 and was made a cathedral in 1877.

St Albans School was founded in AD 948. Matthew Paris was educated there and until 2025 it was the only school in the English-speaking world to have educated a Pope (Adrian IV). Now a public school it has, since 1871, occupied a site to the west of the Abbey and includes the 14th-century Abbey Gateway. One of its buildings was a hat factory, a link with the city's industrial past.

On Abbey Mill Lane, the road between the Abbey and the school, are the palaces of the Bishops of St Albans and Hertford and Ye Olde Fighting Cocks, claimed to be the oldest pub in England.

Between 1403 and 1412 Thomas Wolvey was engaged to build a clock tower in the Market Place. It is the only extant medieval town belfry in England. The original bell, named for the Archangel Gabriel sounds F-natural and weighs one ton. Gabriel sounded at 4 am for the Angelus and at 8 or 9 pm for the curfew. The ground floor of the tower was a shop until the 20th century. The first- and second-floor rooms were designed as living chambers. The shop and the first floor were connected by a flight of spiral stairs. Another flight rises the whole height of the tower by 93 narrow steps and gave access to the living chamber, the clock and the bell without disturbing the tenant of the shop.
