Henry I founded Dunstable Priory in 1132 as a sanctuary for Augustinian Canons. The king cleared a forest to build the town where robbers once hid and granted the priory the lordship of the manor and town.
The priory surrendered to the king on the 20th of January 1540 and received a pension of £60. The church and buildings were initially kept standing but were later plundered of all valuable items and left in ruin after the scheme for a new bishopric fell through.
Thomas Marshall served as prior from 1351 until his death in 1413, a tenure of sixty-two years. He saved his house from serious loss during the Peasants' Revolt in 1381 and secured funds for the education of a canon at Oxford.
St Peter's is one of the best examples of Norman architecture in England, built in the form of a cross with a great tower at the crossing. The west front features a huge entrance with four arches between 1170 and 1190 above a later 15th-century doorway.
On the 23rd of May 1533, Archbishop Cranmer together with the bishops of Winchester, London, Bath and Lincoln pronounced the marriage null and void in the Lady Chapel of the conventual church at Dunstable.
The priory's guest house became a private house from 1545 and is now a Grade II listed building. The Town Council converted the building into a Heritage and Tourist Information Centre.
