Among the documents in Bristol's planning application for the redevelopment of the Clifton site are two 'Heritage Statements' which are retrospective papers about the history of the zoo. They contain maps and photos from different stages of the zoo's development, although I think that some of the dates are not accurate. It is a useful complement to book by Alan Ashy et al published by IZES some years ago. They may be downloaded from the Bristol planning website https://pa.bristol.gov.uk/online-ap...s.do?activeTab=documents&keyVal=RD7NE0DN00J00
