The Duke of Edinburgh officially opened the new elephant house at Whipsnade in 1997.
On 2nd June 1997 to be precise....
It is perhaps worth mentioning here that the Duke of Edinburgh was President of the Zoological Society of London from 1960 until 1977; in this role he would have regularly attended the ZSL AGM at London Zoo.
On 23rd October 1974 the Chinese Ambassador formally presented the giant pandas ‘Ching-Ching’ and ‘Chia-Chia’ to the Duke of Edinburgh, President of the Zoological Society.
Incidentally, after perusing through some copies of the ZSL Annuals reports, I can also add details of a couple of visits by foreign royalty that might be of interest to “zooman64”:-
• 3rd November 1971: King Gustav of Sweden visited Whipsnade
• 5th March 1977: King Hussein of Jordan and King Constatine visited London Zoo
Presumably a more extensive search (that I’ve not yet had time for) would provide details of other such visits.
