Giant Plane tree of Lamanon, Oriental plane tree in Lamanon, France

The Giant Plane tree of Lamanon is an Oriental plane (Platanus orientalis) standing in a field beside the D23 road. It reaches about 25 metres in height, its crown covers 1,250 square metres, and its trunk has a circumference of 8 metres. The pale grey trunk divides low into several large limbs, and the broad, rounded crown fills the sky.

The tree is said to have been planted in the 16th century by Catherine de' Medici during a visit to Nostradamus. It was classified as an artistic natural site and monument on 26 February 1918, and its garden was added to the general inventory of cultural heritage in 1994.

The tree is listed among the Arbres remarquables de France, and its garden has been entered in the general inventory of cultural heritage since 1994. A local tradition holds that Catherine de' Medici planted it in the 16th century while visiting Nostradamus.

The tree stands along the D23 road and is protected with fencing to keep it safe. You can view and photograph it directly from the roadside without needing special access.

The trunk splits into multiple sections at different heights, creating an ellipsoid shape that is uncommon among plane trees. This unusual growth pattern developed naturally over the centuries as the tree matured.
