This attractive well named after St Cedd of Lastingham was constructed in the 19th century, apparently reusing 12th century stone from Rosedale Abbey. Sadly the lions mouth is currently dry.
The wooden plaque reads.
ABBIE LASTINGAE FUNDATOR
OBIIT AD 664 ET SEPULTUS EST
IN ECCLASIA A DEXTRA ALTARIS
My Latin isn’t up to scratch, but Google Translate suggests he established the monastery at Lastingham in AD 654 (other websites suggest AD 658) and was buried in the church to the right of the altar in AD 664.
