Guimaraesで最も古い樹木はどれですか。
Guimaraes' oldest tree by any published measurement 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 below the Paco dos Duques, at about 165 years, and three Himalayan cedars at the municipal cemetery, around 115, are the next oldest confirmed ages here. One tree on this page is probably older than all of them and cannot be ranked: the oak at Santa Marinha da Costa, which the pousada's own guide calls several centuries old and which nobody has ever dated on its own. An olive in the cloister of Nossa Senhora da Oliveira carries the city's founding legend, dated to 1342, but no source ties that trunk to that year and the register records no age for it.
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: Guimaraes and the wider Minho market themselves, with reason, along a Camellia Route, and eighteen trees on one estate is a collection rather than a curiosity. The oak at Santa Marinha da Costa is the interesting gap. Its trees were classified as a group in 1940, and the group's 290 years, measured in 2006, covers six species including a eucalyptus, which cannot have stood there that long, so the figure says nothing about the oak. The olive is the other open question. City tradition holds that a merchant set a crucifix beside a long-dead olive in the square in 1342 and that it turned green three days later, the miracle that named the church, the quarter and the city's coat of arms. The legend is well documented. That today's tree is the miracle tree is not, so the age is left open rather than implied.
