My vote would go to a secret garden or walled garden – perhaps part of a larger royal garden. [ http://landscapenotes.com/2013/03/22/st-johns-lodge-the-secret-garden/ ] This post is on the secret garden at St John’s Lodge. Although I am not personally familiar with this garden – nor the one at Kilver Court – it is the type of garden I am thinking of? [ http://www.kilvercourt.com/secret-gardens ] Charlton Manor used to have an abandoned secret garden with old roses…I am sure that its use by the Primary School has quite the same romantic associations.
