There is evidence of prehistoric occupation in the area, particularly along the
Icknield Way which forms the northern boundary of the parish. Five
bowl barrows dating to the
Bronze Age (c. 2000–700 BC) are clustered together on Therfield Heath. The
Domesday Book of 1086 records 52 households at Therfield, including a priest, suggesting that Therfield was a parish by then. Therfield at that time was owned by
Ramsey Abbey, to the north. The
manor of Therfield had been given to Ramsey Abbey in the early 11th century, and remained in its ownership until the
dissolution of the abbey in 1539. The manor was then claimed by the crown, which subsequently granted it to
St Paul's Cathedral in London. A depiction of the
Stuart royal arms was retained from the earlier building. North-west of the church, a
motte and bailey castle known as Tuthill was built in the mid-12th century. It seems likely that the castle was built around 1143–1144 following attacks on the area by
Geoffrey de Mandeville, 1st Earl of Essex, during the civil war of the
Anarchy (1138 to 1153). The castle was coupled with a defensive enclosure surrounding the pre-existing village to the east of the castle. The castle did not last long, falling into disuse in the early 13th century. Archaeological excavation of the castle site was carried out in 1958, after which the site of the motte continued to be protected, but much of the bailey area was levelled in 1960.
Therfield Chapel Therfield Chapel was established as a congregation of Protestant dissenters (the "Independents") in 1836. The current chapel building was built in 1854. For a time the chapel was known as Therfield Congregational Church, being affiliated to the
Congregational Union. When in 1966 the Congregational Union was replaced by a body which espoused more liberal views, the chapel seceded and became affiliated first to the Fellowship of Independent Evangelical Churches (FIEC), and then to the Evangelical Fellowship of Congregational Churches (EFCC). ==Geography==
