The Society was founded in 1857 and is now a registered charity with the following objects: To promote the study and publication of archaeology and history in all their branches, especially within the ancient county of Kent. Much of the County has been lost to London since 1857 so the “ancient county” is treated as including the London Boroughs of Bexley, Bromley, Greenwich and Lewisham, as well as Medway and the administrative county.The Society’s interests are not confined to fieldwork. Its objects cover archaeology and local history in the widest sense. They include historic buildings, genealogy, industrial archaeology and local history though it is not always active in all these fields. The Society has over 1,200 members, many outside the County or overseas, and welcomes new members who support its objects.
