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 , 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.
