The Day of Syn originated in 1964 when the Parish Church of St Peter and St Paul urgently needed funds to pay for the renewal of the church roof. It was decided a pageant based on the Doctor Syn stories would be the theme. Russell Thorndike, the author of the Syn stories, who had resided in the village of Dymchurch, gave a written document, allowing the title 'Dayof Syn' to be used as the title of the pageant, to the church.
It was a great success and another one was planned by the church for the following year. This again was well received by visitors and villagers alike. In 1966, as the event was becoming too much for the Parochial Church Council it was decided that a committee made up of the P.C.C. and local organizations be formed.
The committee decided to hold the Day of Syn every other year with a pageant and fete. The idea was that the pageant would bring in people and at the fete local charities would have stalls and sideshows and be allowed to raise funds for their organizations'.
Over the years the Day of Syn has grown from being just one day, the August Bank Holiday Monday, to a weekend event The event brings in thousands of visitors from all over the country and abroad, even as far as Australia and the U.S.A. One thing about the Day of Syn is that the event is totally free, no payment is needed to enjoy the pageant and the other entertainments put on by the Day of Syn Committee.
