Frogholt is a hamlet near Folkestone in Kent, England, on the banks of the Seabrook stream. There are eight houses in Frogholt. The hamlet is part of a conservation area and lies very close to the larger villages of Newington and Peene. One of the houses, Old Kent Cottage, was likely built in the 14th century. Claims have been made that it is even older but since it is constructed as a medieval hall house with parlor and solar this is unlikely to be the case. It is reputed to be the oldest thatched cottage in Kent and is said to have been a safe haven for Archbishop Thomas Becket during his feud with Henry II though this is impossible to verify.
