St Winifred's holy well, one of the wonders of Wales, sends up water at the rate of 21 tons a minute, of an almost unvarying temperature, higher than that of ordinary spring water.
Other public buildings are St Winifred's (Catholic) church and a convent, a town hall and a market-hall.
Under faith healing in a wider sense may be included (I) the cures in the temples of Aesculapius and other deities in the ancient world; (2) the practice of touching for the king's evil, in vogue from the 11th to the 18th century; (3) the cures of Valentine Greatrakes, the "Stroker" (1629-1683); and (4) the miracles of Lourdes, and other resorts of pilgrims, among which may be mentioned St Winifred's Well in Flintshire, Treves with its Holy Coat, the grave of the Jansenist F.
The public buildings include St Margaret's (1862) and St Winifred's (1883), the parish churches of Mountain Ash and Penrhiwceiber respectively; old and new town halls (1864 and 1904), cottage hospital (1896), and a library institute and public hall erected in 1899, at a cost of £8000, by the workmen of Nixon's Navigation collieries.
In September, shortly before the expected meeting of parliament on the 3rd of October, Garnet organized a pilgrimage to St Winifred's Well in Flintshire, which started from Gothurst (now Gayhurst), Sir Everard Digby's house in Buckinghamshire, included Rokewood, and stopped at the houses of John Grant and Robert Winter, three others of the conspirators.
