Medieval pilgrimage well, the Welsh Lourdes.
By legend a spring rose where St Winefride’s severed head fell — a 7th-century woman restored to life, the story goes, by her uncle St Beuno. Pilgrims have bathed here ever since, which is how the town got its name, Holywell, and how the well earned its tag as the Lourdes of Wales; it counts among the oldest continuous pilgrimage sites in Britain. A fine Perpendicular chapel of around 1512–25 stands over the spring. Cadw charges admission, and you can still step into the water or fill a bottle at the tap. Winefride’s relics were later carried off from Gwytherin to Shrewsbury.
