 The site was visited, not only on account of the reputed medicinal properties of the water, but also for the 40 days' remittance of penance granted by the Pope to those who on the three holy days of Pentecost (Whitsun and the following two days) made their confession and offered prayers at St Blaise's Chapel.After the Reformation, the oratory fell into ruin and the well into disuse – during the course of time becoming buried and forgotten.However it was rediscovered in 1754, by a Mr. Harwood, the Bishop's chaplain, who noticed a ""yellow ochrey sediment, remaining in the tract of a small current, leading from the spring to the corner of the moat, with the waters of which it used to mix"".
