Rediscovered in 1754 (by the Bishop’s domestic chaplain, a Rev Mr Hardwick); a spring seeping into the moat was identified as a chalybeate spring, complete with buried ancient oak steps.
“Chalybeate” means that the water contains minerals, usually iron. There was a fashion for ‘Spa’ cures from about 1600AD onwards with towns like Bath and Tunbridge Wells being built around them, catering to the rich ‘taking the waters’. The Pulham Rock site says that it was supposed to possess healing properties capable of curing almost everything, including:
‘ . . . the colic, the melancholy, and the vapours. It made the lean fat, the fat lean; it killed flat worms in the belly, loosened the clammy humours of the body, and dried the over-moist brain.’
In 1754 it was roofed with thatch over 6 pillars – replaced with tile roof by the Lord of the Manor, Coles-Child, but this has not survived into modern times. The spring is chalybeate, and from a perched water table that also seeps out by Churchill Theatre and along the base of Martin’s Hill. St Blaise was the patron saint of wool carding (bishop of Sebaste in Armenia with a gruesome death) and quite popular in medieval times.
The Pulhamite website describes the spring as follows:
“The Bishops built a well a few hundred yards from the chalybeate spring, and marked it with oak trees. It was about 16 inches in diameter, and the canopy had a roof of thatch, thus heightening the picturesque appearance of the scene, as shown on the left of Fig 2. The water rose so slowly, however, that it took nearly four hours to yield a gallon of water. There was an orifice in the side of the retaining wall that enabled surplus water to trickle over into the adjacent moat – or small lake – that borders the grounds of the palace. It eventually became a place of pilgrimage, and an oratory in honour of St Blaise, the patron saint of the wool trade, was built close by.
After the Reformation, however, the oratory fell into ruin, and the well into disuse, although it is not clear whether they ran out of pilgrims because they died of the colic, melancholy, the vapours or old age while they were waiting for their cups to be filled with chalybeate water, or as a result of drinking it. “
