Tewin, a village with a population of about 2000, is located in Hertfordshire part way between the towns of Welwyn Garden City and Stevenage.  Some of its inhabitants work locally, while many commute to London each day.  The village dates back, at least, to Anglo Saxon times and its name has its origins in Anglo Saxon English.  Tewin has most of the features typical of English country villages, a Church, two pubs, a village green, a red telephone box and a shop.

A record of people resident in the village during the year 2000, to be known as the Tewin Millennium Register, has been copied by a local calligrapher, bound in leather and put on display in a case in the Church.
