Bedgebury Park School for Girls, in Kent, was evacuated to Nannau during World War Two (on May 24th, 1940).
Information courtesy of Alan S. Nipper: “This private school for girls moved to Wales in 1940, returning to Goudhurst, Kent in 1945. The school was founded in 1920 and closed circa 2002. I believe the younger pupils were housed in Llanelltyd . They and the seniors were also given facilities at Dr Williams School.”
