The Sign
The main feature on the sign is the arms of the Reydon family, topped with the church of St Mary showing the east wall. The yellow ears supporting the sign probably represent rye related to the village name. The sign was erected to commemorate the Queen's Silver Jubilee in 1977 and the wedding of Charles and Diana in 1981.

The Name and Population
The population was 507 at both the 2001 and 2011 census. It was called Reindune, Rienduna in the Domesday Book and Reindun in 1254. The name means "The hill where rye is grown", from Old English.

Other Points of Interest
During World War II an airfield was built in this area, which was initially known as United States Army Air Forces (USAAF) Station 157, later becoming RAF Raydon.

The northern part of the parish contains several nature reserves; Raydon Great Wood, Long Wood, Squares Grove and Tom's Wood, all of which are ancient woodland. The abandoned Hadleigh Railway previously ran through the Great Wood, with a station at Raydon Wood. The line is now also a nature reserve.
