A park in Amsterdam has begun planting 150 saplings from an ancient chestnut tree that once cheered Anne Frank as her family hid from the Nazis.

The Jewish teenager wrote about the tree in her diary as a rare connection to nature during the 2 years her family hid in cramped conditions in Amsterdam before their betrayal.

Frank died of typhus in the Bergen-Belsen concentration camp in 1945, aged 15.

The 150-year-old tree is now dying but will eventually be replaced with one of several clones that have been taken from it.

City councilwoman Marijke Vos planted the first sapling in the Amsterdamse Bos park Friday.

Others will be planted around the world, including countries such as the U.S.
