Ancient trees in Finland
This far north, cold winters and thin, rocky soil slow a tree down, so Finland's list runs on rarity more than raw age. We map 14 trees in 3 cities here. The oldest of them is Paavola's Oak in Lohja, at 300 to 400 years.
Helsinki only became the capital in 1812 and most of its ten protected trees are Finnish size records, a thickest willow, a thickest park lime, rather than genuine veterans. Turku's Kalm's Oak earns its place differently: planted around 1750 in a garden the Great Fire of 1827 burned to the ground around it, and still called the city's oldest tree. Outside both cities stands Paavola's Oak on Lohjansaari, documented by the photographer I.K. Inha over a century ago and repeatedly called the most beautiful tree in the country since long before anyone here was searching the internet for it. Twelve trees mapped so far, across Helsinki, Turku and Lohja.
