 With the construction of the current cathedral and the bishop's palace in the first half of the 13th century, under the direction of Bishop Reginald and later Bishop Jocelin, a native of the city, Wells became the principal seat of the diocese.Wells was listed in the Domesday Book of 1086 as "Welle", from the Old English , not as a town but as four manors with a population of 132, which implies a population of 500–600.Earlier names for the settlement have been identified which include "Fontanetum", in a charter of 725 granted by King Ina to Glastonbury and "Fontanensis Ecclesia".
