When William de Warenne, the castellan of Castle Acre, and his wife Gundrada visited the French monastery of Cluny in 1077, they were struck by the beauty of its buildings and the holiness of its monks.
Soon after their return to England, de Warenne offered to establish a Cluniac monastery in England and granted land close to his castle at Lewis, where St Pancreas Priory became the first Cluniac house in England. In 1089 - after his wife Gundrada had died in childbirth - de Warenne established a second Cluniac priory at Castle Acre, which soon grew into an important local institution.
Ruined after being suppressed in 1537, what is left of the priory today still allows us a glimpse into its long history.
On its foundation (and throughout its history) the priory received grants of land and money not just from William de Warenne, but from other nobles and merchants who hoped to ensure their salvation. So building works for a church and other monastic buildings were soon under way. The Cluniac order considered beauty a form of worship and that belief can be detected even in the priory's ruins.
The church, built in the 12th century, had been planned to resemble the church of the mother house in Cluny. Only the west front now remains, but the great gateway and the tiers of intersecting arches show that austerity had no part in this church.
During the early Middle Ages, the priory grew wealthy. Royal grants from both King Henry I and his grandson Henry II exempted it from tolls, which was a very valuable benefit for a monastery with extensive lands.
Nobles, merchants and even royalty - such as King Henry III and King Edward I and his Queen Eleanor - stayed at Castle Acre Priory while on their way to the shrine at Walsingham.
And most of these visitors would have walked through the late medieval gatehouse towards the prior's lodgings.
Timber-framed and decorated with flint, it stands guard over the priory's remains. Inside, the prior's lodgings still show traces of wall paintings and the huge fireplaces seem to hint at home comforts and cosy evenings.
Accommodating about 35-40 monks during its heyday, the Black Death, a sheep epidemic and quarrels with the priory in Lewis all affected Castle Acre's fortunes.
In the aftermath of the Black Death people seemed less drawn to the religious life and many monasteries struggled to find a sufficient number of monks to perform the daily offices and administer the large estates they had accumulated. Castle Acre Priory was no different and when the priory was dissolved in 1537 only the prior and 10 monks are recorded as living here.
Fortunately for us, parts of the Cluniac house have survived the dissolution and the ravages of time. What is left of Castle Acre Priory is now being cared for by English Heritage. Check out this page for opening times and events.
