As part of the creation of a Tudor garden within the walled garden associated with the Cowdray ruins, planning permission (EB/04/03667/FUL) and Scheduled Monument Consent was obtained for the erection of a greenhouse. A condition attached to both these consents was for archaeological observation and recording of any associated groundworks. West Sussex Archaeology have been appointed to carry out such archaeological works and this report details the ensuing results. The archaeological observation of groundworks took place on the 2nd February 2005. The existing topsoil of the garden covered earlier features dug into the sand geology. The precise nature of these features it was impossible to determine due to the limited nature of the investigation, but several phases of activity were represented. It is perfectly possible that some of these features may relate to pre-1700 gardens or structures on the site, some to the walled garden created c.1700 and some, notable the topsoil, to a 19th century re-working of the garden
