What is the oldest tree in Guimaraes?
Guimaraes' oldest tree, on the best evidence available, is one of the eighteen camellias in the terraced gardens of the Palacio Vila Flor, planted around 1830 and measured at roughly 195 years in Portugal's tree register. Two plane trees on the lawn below the Paco dos Duques, at about 165 years, and three Himalayan cedars at the municipal cemetery, around 115 years, are the next oldest confirmed ages on this page. An olive tree in the cloister of Nossa Senhora da Oliveira carries the city's own founding legend, a miracle dated to 1342, but no source ties this specific trunk to that year and the register itself records no age for it, so it is not the answer here.
The camellias, the planes and the cedars all trace their ages to the same 2011 classification pass by Portugal's forestry institute, which is why they agree with each other to within a plausible margin. The camellias are worth the walk regardless of the number attached to them: Guimaraes and the wider Minho region market themselves, with reason, along a Camellia Route, and eighteen trees on one estate is a serious collection rather than a curiosity. The olive tree is the more interesting story. City tradition holds that a merchant returning from Normandy in 1342 set a crucifix beside a long-dead olive trunk in the square, and that the olive turned green again three days later, a miracle that gave the church behind it, and so this whole quarter of the city, the name Nossa Senhora da Oliveira, Our Lady of the Olive Tree. The legend is real and well documented. What cannot be verified is that today's tree is the miracle tree, so the age is left open rather than implied.
