Located on the southern bank of the River Little Ouse, six miles west of Diss, in 2005 its population was 230. The village of Blo' Norton lies on the Norfolk side of the river.

Trappetes' Cross
A 16th century stone cross located to the west of the village near the junction of Hopton Road and Mill Road, an area formerly known as Cross Green. Only several blocks of ashlar, forming the base and a small part of the shaft, remain in the orchard belonging to The Evergreen Oak, the early 16th century former public house. Moved from fields to its present location, the original site of the Trappetes' Cross has not been identified. The cross was bequeathed to the village by John Cole of Thelnetham in his will of 1527 in which he gave the instruction “Item 1.I will have a new crosse made accordinge to Trappetes' Crosse at the Hawelanesende and sett upp at Short Groves ende, where the Gospell ys sayde upon Ascension Even, for which I assigne xs". He further directed that a certain farm-rent should be applied yearly to the purpose of providing “a bushel and halffe of malte to be browne, and a bushel of whete to be baked to fynde a drinkinge upon Ascension Even everlasting for ye parishe of Thelnetham to drinke at the Cross of Trappetes''”. Reference to the cross can still be found in the names of nearby dwellings such as Trappetes Cross Cottages and Cross Green Farm.
