The Sign
The sign was erected in 2000 to celebrate the Millennium, designed by Mary Lacey and made by Trevor Rumsey. There are four main subjects on the sign, including the church of All Saints in the top left with a stag deer to its right representing the forest all around, a Suffolk Punch horse in a ploughed field in the bottom left and a Churchill tank known as the 'Suffolk' in the bottom right which represents the area being used as a training ground. The swirls in the sign frame at the top could represent the sunrise above the church and the branches of the trees in the forest above the stag.

The Name and Population
The population was 309 at the 2011 census. The name could mean "Southern stream", from Old English. It was called Sutborne 1042-66 and Sutburna, Sutburne in 1086.

Other Points of Interest
Sudbourne Hall has had many owners over the years, probably all represented in the church.

During World War II Sudbourne and the neighbouring village of Iken were used as a battle training area in advance of the D-Day landings in June 1944. The inhabitants were relocated returning sometime after the war finished.
