This section of the website was originally set up as a separate website in 2008, as a collaboration of CAT and the Department of Computer Science and Electronic Engineering of the University of Essex to exploit modern technologies in archaeology. In June 2025 the data was migrated from its old system running on the University’s servers to be a fully integrated part of our main website.

The plan is to create a free resource to support and encourage interest in the archaeological remains of Colchester and to make information about archaeological research and discoveries in the town as widely and easily available as possible. The core of the material here is made up of almost all the publications and fieldwork reports (archive and published) of the Colchester Archaeological Trust dating back to its establishment in 1963 when it was known as the Colchester Excavation Committee.

The ultimate aim is to provide reports on every fieldwork project undertaken by the organisation since its beginning. Other Colchester material is also being added, with the long-term intention of making the site as comprehensive as possible in terms of archaeological research in Colchester. In particular, the additional material will include articles about aspects of Colchester published by the Essex Archaeological Society in Essex Archaeology and History and earlier in the Transactions of the Essex Archaeological Society.

There is much to do, but it is hoped that the site content will eventually have sufficient depth and richness to become a useful research tool in itself.
