The story that haunts this land

Your quest begins in front of the majestic St Albans Cathedral (West Front, AL1 1BY), built in 1077 by Abbot Paul of Caen on the very site of Saint Alban's martyrdom. This 11th-century St Albans Cathedral, with its 84-meter nave, one of the longest in medieval England, was elevated to cathedral status in 1877. Here you will look for the first traces of Britannia's first Christian martyr, whose relics were rediscovered in 1129, a key event for the medieval pilgrimage of Saint Alban. The English Perpendicular Gothic architecture surrounds you, and clues will guide you towards the mysteries of early Christians.

Continue your exploration towards the Roman Wall of Verulamium, an imposing relic built around 200 AD from sandstone and limestone. Originally 2.4 km long, with a thickness of 2.1 meters and an estimated height of 6-7 meters, this wall protected Verulamium, the third city of Roman Britannia. Visible sections today, including 200 meters near Verulamium Park, incorporated four main gates and eight watchtowers. Your investigation of this Verulamium Roman archaeological site will reveal how this Roman city in Britannia resisted attacks, particularly during Boudicca's Iceni revolt in 60-61 AD, before being rebuilt.

The path then leads you to the Roman Theatre of Verulamium, built around 140 AD. It is one of the few preserved Roman theatres in Britain, with a diameter of 65 meters and a capacity of 2,000 spectators. Excavations led by Mortimer Wheeler in 1934-1936 and 1961-1963 uncovered Latin inscriptions attesting to the presence of Roman magistrates and religious cults. Nearby, 2nd-3rd century mosaics and the 4-hectare Roman Forum, the administrative and commercial heart of the city, immerse you in the daily life of this Roman city in East England. Every detail will be crucial for your progress in this GPS treasure hunt.

Your journey takes you back towards the center of St Albans, where the Abbey Gateway, built around 1365, stands proudly. The only surviving structure of the Benedictine abbey's enclosure, this 15-meter-high gate is an example of English Perpendicular Gothic architecture, fortified with machicolations and arrow slits, reflecting the political tensions of the Hundred Years' War. A Grade I Listed Building since 1952, it holds secrets. Not far, the St Albans Clock Tower, built between 1403 and 1412, is one of England's oldest urban clock towers. 21 meters high, it served as a municipal prison and its original 15th-century clock was restored in 2002-2003.

Finally, your investigation leads you to the Martyrdom of Saint Alban Monument, the traditional site of his execution around 303 AD under Diocletian. It is here, on Hollywell Hill, that Britannia's first Christian martyr is said to have sealed his fate, a story documented by Bede the Venerable in his Historia ecclesiastica gentis Anglorum. An 11th-century commemorative chapel was replaced by the current cathedral, solidifying St Albans as a major pilgrimage site. Thanks to this interactive St Albans tour, you will have not only uncovered the secret of the first martyr but also discovered the history of St Albans and the monuments of East England, transforming this walk into a true exploration of East England's heritage.
