The Plante Promenade is a 4.5-kilometre-long alley park created on the site of an outdated railway line that closed in 1969. The park starts at the Bastille Opera and runs to
Bois de Vincennes. There are old and modern buildings, there is a bicycle track. Some sections of the park offer panoramic views of Paris.
The Plante Promenade is the only elevated park in the world.
