Thornage has an entry in the Domesday Book of 1085. In the great book Thornage is recorded by the name ‘’Tornedis’’, the main land holder being Bishop William. The survey also lists 3 mills.
Thornage Hall is a former grange of the Bishops of Norwich. There has been a manor house on this site since the time of the Normans. The hall was built c. 1482 by Bishop Goldwall of Norwich. After the dissolution of the monasteriesthe hall was given to Sir William Butts by Henry VIII. In the 17th century both ends of the Hall were demolished and remodelled, but the hall windows and doorways in the centre block were retained. In 1988 a 17th-century sewer tunnel was rediscovered. Nearby there is a large brick dovecote, dating from 1728, and barns of flint and brick dating from 1718 and 1727.
Thornage Watermill
The watermill is located to the north east of the village and stands on the river Glaven whose course was altered to enable construction of the mill on a site able to hold the mill dam without flooding the surrounding area. A watermill was first recorded on this site in the Domesday Book; in the 13th century it was known as Feldmille. The present watermill, built of Norfolk red brick with a pantile roof, stopped working in 1938 and the building is now a private residence. In its working order the watermill had a breastshot 13' x 6' wheel, made entirely out of wood, which powered 4 pairs of stones driven from above and controlled by two sets of flyball governors. Three pairs of French burr stones still remained in 2011, along with some of the mill machinery, which has been incorporated into the living area of the private residence conversion.
The chancel of the present Parish Church of All Saints was constructed in the early part of the 14th century. The church was substantially renovated in 1898 and in 1904. Three Norman windows can be seen in the nave and the chancel. At some time the church had a south aisle, as the blocked up arcade shows. Inside the church is the tomb chest of Sir William Butts, who died in 1583. His father, also named Sir William Butts, was the chief physician in the household of Henry VIII. The church's communion plate is very ancient, as is the chalice, on which are inscribed the words "was the gyfte of John Butts, and Margaret, his wife - 1456".
