The thatched well (below) in the village of East Marden is a well-known attraction in the South Downs, not far from Chichester. The village is recorded in the Domesday Book (as Meredone) and St. Peter's Church (in the background) is from the 12th century.

According to the information on this pin and this South Downs National Park Authority pdf, the well is 200 feet deep, has an 18th century pump and was the only source of water in the village until 1924.
However, the story before the 18th century is unclear. The article Secret Villages of the South Downs relates this story on the well and Saint Richard of Chichester (d. 1253):
He is said to have performed a minor miracle hereabouts, when, in answer to the prayers of the villagers during a drought, he provided a spring of cold, clear water. Could this be the origin of the thatched well, which forms a landmark in the centre of East Marden to this day?
Is there anything in the historical record about whether the well pre-dates the pump (i.e. the water was brought up with buckets on a rope)?
Also, for how long has it had a thatched roof?
My reason for asking this (perhaps seemingly obscure) question is that I spent much of my childhood in this village. Unfortunately, none of the people I knew there at the time are still there (and I now live on the other side of the world).
