Uncover the cipher William the Conqueror hid at Pevensey before his 1066 landing. Decode clues across Roman ruins and castle walls to reveal the secret orders that launched the Norman Conquest.
📱 1 to 10 phones · 1 team per phone · Independent codes
In September 1066, William the Conqueror stood on Pevensey's shores, his fleet poised to claim England's throne
Step into the shoes of Robert de Mortain, William's half-brother and builder of Pevensey's keep. Your mission: secure the remnants of the 1066 landing before a Saxon plot rewrites history. You arrive in Pevensey, the first stop on an investigation that will take you 1.5 km through the most strategic sites of the Norman invasion in Sussex. At each stage, open your phone: augmented reality clues appear on the castle walls, the bay's pebbles, the stones of St Nicolas Church. A medieval map appears on High Street, the ghost of a Norman soldier emerges from the churchyard to give you a coded message, the spirit of Pevensey Levels whispers the secret of an ancient hiding place. Over approximately 135 minutes, at your own pace, you trace your own Norman Pevensey — the one from history books blended into the landscape. More than an outdoor escape game: an interactive visit immersed in 2,000 years of history, with anecdotes revealed at each stop and confidential sites that classic guides overlook.
You're not just buying an escape game. You're carrying a living guide — historical anecdotes, forgotten legends, key monuments, hidden architecture — unfolding as you go.
At each stop, places ordinary guides miss — secret façades, sculpted crests, alleys steeped in history.
Every riddle is rooted in a real historical fact or local legend. You leave with dozens of stories to tell.
Learn to read buildings — flamboyant Gothic, Baroque, Art Deco — like a real art historian, while having fun.
Walk through the city like a novel's character — every alley becomes a stage, every square a theatre.
A voice walks with you at every step, tells the story of each place, reads clues, adds a cinematic feel.

Your quest begins at Pevensey Castle, the ancient Roman fort of Anderitum, built around 290 AD. This 1.6-hectare coastal fort, with its 3-meter thick walls, was captured by William the Conqueror in 1066, becoming the first Norman castle in England. In 1087, it was transformed into a motte-and-bailey castle under the impetus of Robert de Mortain, who had a stone keep built there in the 12th century. English Heritage manages this Scheduled Ancient Monument since 1925, and you will explore the 13th-century barbican and the ramparts that witnessed the landing of the future King of England, according to the Anglo-Saxon Chronicle, on September 28, 1066.
From the castle, you reach Pevensey Bay, this 5 km pebble beach that was the scene of William's historic landing. Orderic Vitalis, in his Historia Ecclesiastica (circa 1110), reports that 7,000 men landed on English soil there. Once a Roman harbor, this bay is now a protected area, adjacent to the Pevensey Levels. A 900th anniversary memorial, erected in 1966 near the castle, marks this event that shaped Sussex and England for centuries to come.
Your journey then takes you to St Nicolas Church, a Norman parish church built around 1080-1100. With its 12th-century nave and chancel, it served as a chapel for the guardians of Pevensey Castle in the Middle Ages. Its 13th-century tower, 24 meters high and restored in 1865, dominates the landscape. Designated a Grade I listed building in 1954 by Historic England, the church houses a commemorative plaque of the 1066 landing, a silent witness to the events that marked this historic land.
The Churchyard of St Nicolas Church, a historic cemetery adjacent to the church, offers a direct view of Pevensey Castle, less than 200 meters away. With its 13th-century tombs and Grade II listed funerary monuments since 1982, this site was used as a refuge during the Battle of Hastings in 1066. Exploring Pevensey High Street, you will discover 15th-century timber-framed houses and the 6-meter high East Gate, leading to the castle, in this conservation area since 1971.
Your investigation concludes with the Pevensey Levels, this 3,967-hectare wetland area, drained in the 13th century for agriculture. A nature reserve managed by Sussex Wildlife Trust since 1964, it is home to migratory birds and medieval dikes, remnants of post-1066 Norman defense. Roman and Saxon archaeological excavations took place there in the 1930s. This thematic circuit will have immersed you in the heart of Pevensey's history, from its Sussex monuments to the traces of the 1066 invasion, enriching your understanding of Sussex's heritage and this English Heritage site.
