What is the oldest tree in Barcelona?

The holm oak on Carrer de l'Encarnacio predates the neighbourhood that grew up around it. Gracia was a scatter of farmhouses when the tree was young, and it appears on the city's 1845 maps standing on rural land known as the Pla del Bonpa, tied to a farmhouse called Can Vidalet. Dendrochronologists, tree-ring specialists, later dated it to roughly 250 years old, making it the oldest tree in Barcelona and the plain it sits on. The tree nearly did not survive to be dated: a development plan for the historic Casetes de l'Encarnacio around it triggered a three-year local campaign, and the oak was formally catalogued as a Tree of Local Interest in 2019 specifically to stop the bulldozers. The garden around it opened to the public in April 2021, though only the facades of the original houses could be saved. For grandeur over paperwork, Barcelona's biggest tree by volume is a different story entirely: a Rehder's wingnut in the botanical garden's Sot de l'Estany ravine, reaching roughly 40 metres in a hole in the ground nobody visits. Getting to the oak: Fontana station on the L3, then an eight minute walk into Vila de Gracia.
