Ruth Gibson joined the Henley Archaeological & Historical Group in the early 1980s and became interested in historic buildings through the nationwide barns survey run by SPAB ( Society for the Protection of Ancient Buildings). To find out more about the reason for the abundance of historic barns and other farm buildings, most of them vacant, or on the verge of residential conversions, she went to Reading University and got an honours degree in Archaeology and History, specializing in farming history. Her dissertation on the Harpsden Court Estate was based on the 1586 survey/mapĀ of this estate by the Blagrave Map makers family of Reading. She then worked as an Historic Buildings Officer for Bedfordshire County Council, Aylesbury Vale D.C and the National Trust. She has been recording medieval buildings in and around Henley for the past 30 plus years and is our acknowledged expert.
