What is the oldest tree in Oslo?

Oslo's city-planning magazine names the Munch-eika as the clearest example of the value, and the fragility, of the city's oldest trees: an oak in the Montebello area estimated at 500 to 600 years old, with a trunk roughly eight metres around, already mature centuries before Christiania grew into the modern city that eventually surrounded it. Its name almost certainly points to Edvard Munch, whose home and studio at nearby Ekely stood a short walk away for the last decades of his life, though no source this project could find documents the naming story itself beyond that geographic coincidence. What the same city article makes explicit is how quickly a tree this old can still be lost: root damage, soil compaction or simple neglect can undo five centuries of growth in a handful of years, which is why Oslo's own planners use the Munch-eika to argue for protecting old trees before they become emergencies rather than after. It stands today as one of very few individual Oslo trees old enough to predate the city's own written tree records.
