The Thatcham Historical Society exists to promote an interest not only in the local history of Thatcham and district but also in historical matters in general.

A regular series of talks by invited speakers takes place throughout the year. They have a wide range of subject matter in the talks by interpreting "historical" relevance very freely. Past talks have covered reports of visits to the ancient civilisations of the Middle East and South America, aspects of industrial, transport and agricultural history, as well as aspects of the local history of Thatcham and District. The latter where possible are given by speakers who are involved in local research. Most talks are illustrated by slides and some have given members a chance to identify (or guess at!) the purpose of certain historical artefacts from local collections.

They also organise a day trip each summer to a place which has strong historical associations, for instance Rochester, Bristol and Southampton have been visited in recent years. An afternoon guided tour of a local town or place of interest is often organised in the autumn.

None of this would be possible without the support of the committee, who organise talks and trips.
