The swannery, at Chesil Beach, was founded by Benedictine monks to provide food during winter months. It currently houses 800 birds.
A series of five commemorative stamps by the artist David Gentleman, to be issued next Tuesday, shows swans, cygnets and eggs at the swannery.
The duck decoy once used to capture ducks for the table - and now used to allow them to be ringed for research and released - is depicted on the 24p stamp (below) with a cygnet in the foreground.
