Wat is de oudste boom van Salamanca?

The date comes from a documented donation rather than a growth estimate: a local newspaper records that Federico de Onis y Onis gave the tree to the university in 1870, and the regional register of notable trees lists a matching sequoia in the same courtyard, though no single source explicitly ties the register entry to the newspaper's account, so the identification, while near-certain, is not stated outright anywhere. What makes the age notable is the climate it has survived: coast redwood belongs on California's foggy northern coast, where it is the tallest tree species on earth, not on a dry plateau 800 metres above sea level that bakes through the summer. A redwood holding on in a walled courtyard for a century and a half is doing something the species never evolved to do. It shares the city with two younger conifers a world away from home, a giant sequoia planted facing the cathedral in 1976 and a disputed cedar in the Alamedilla park, but neither approaches its age.
