The festival is usually held in the third week of July, and features a parade of banners from trade unions, a memorial service, speeches and music.
Each year a wreath is laid at the grave of James Hammett, one of the martyrs, in the churchyard of Tolpuddle parish church.
The main speeches and performances take place on a small stage in front of the Tolpuddle cottages and museum, with audience space on the green.
The adjacent field, as well as having camping space, has a marquee, Workers Beer Company bar and merchandise stalls.
Musicians have included Emmanuel Jal, She Drew The Gun, Billy Bragg, Dick Gaughan, David Rovics and Graham Moore.
