St. Ann's Well is set on the slopes of the Malvern Hills above Great Malvern. It is a popular site on a path leading up to the Worcestershire Beacon and lies on the final descent of the Worcestershire Way. The spring or well is named after Saint Anne, the maternal grandmother of Christ and the patron saint of many wells. A building that dates back to 1813 houses the well or spring. Malvern water flows freely from an elaborately carved water spout. The building also hosts a cafe. During the early 20th century, the now-defunct Burrows company bottled and sold Malvern Water from this source under the "St Ann's Well" brand.
St Ann's Well is a natural spring which Palmer suggests may have been dedicated to Anu, a Celtic water goddess. A 19th-century antiquarian speculated that "St Ann's Well — in its primary form means simply 'the well dedicated to the sun'".
According to James Nott one of the most important events in the history of Malvern was the arrival of St. Werstan, who established a cell on the hillside near St. Ann's Well. St. Werstan was a monk of the Saxon monastery of Deerhurst in Gloucestershire which was destroyed by the Northmen. Werstan escaped and fled through the Malvern Chase, finding sanctuary on the Malvern Hills. Legend tells that the settlement in Great Malvern began following the murder of St. Werstan. Although the legend may be monastic mythology historians have concluded that he was the original martyr. St Werstan's oratory is thought to have been located on the site of St Michael's Chapel which is believed to have stood on the site of Bello Sguardo, a Victorian villa. Bello Sguardo was built on the site of Hermitage Cottage. The cottage was demolished in 1825 and ecclesiastical carvings were found within it. A Mediaeval undercroft, human bones and parts of a coffin were also uncovered. A 15th-century stained-glass window in Great Malvern Priory depicts the story of St. Werstan, with details of his vision, the consecration of his chapel, Edward the Confessor granting the charter for the site, and Werstan's martyrdom.
