The Plane of the Fontana dei Dodici Mesi over 200 years, by the regional register's age band
London Plane (Platanus x acerifolia). Forty metres, and nothing in Turin is taller.
Turin's oldest tree and Turin's tallest tree both stand in this park, a few hundred metres apart along the Po.
The oldest is an oak behind the Castello del Valentino, past two hundred years by the regional register and the exception in a city where every other tree that old is a plane. The tallest is a plane by the Fontana dei Dodici Mesi at forty metres, and nothing in Turin beats it. A third plane, six metres round, is the widest trunk in the park, and a hackberry stands alone on open grass, which is why its crown is so even.
All 5 stand in Turin, which maps 8 remarkable trees in total.
Pedunculate Oak (Quercus robur). Every other tree in Turin that the register dates past two hundred years is a plane.

London Plane (Platanus x acerifolia). Forty metres, and nothing in Turin is taller.
Mediterranean Hackberry (Celtis australis). This one stands by itself on open grass, which is why it looks the way it does.
London Plane (Platanus x acerifolia). The medieval village beside this tree was built in 1884 and there is nothing dishonest about it.
