Visit the Pere Lachaise cemetery in Paris and chestnut trees
greet you as you wander among graves of luminaries such as Oscar Wilde and Jim
Morrison.
When Anne Frank was in hiding from the Nazis in Amsterdam,
the view of a monumental chestnut tree was one thing that cheered her up.
In Cambridge, England, the two-century-old chestnut standing
outside King's College chapel has become a beloved icon.
In all those places — and over much of Europe — the horse
chestnut tree is under threat.
