Nobody can date this oak, because the wood that held the answer has rotted away.
Ancient trees in Slovakia
Slovakia's most-told tree story belongs to Bojnice, where a linden behind the castle is tied by tradition to a visit from King Matthias Corvinus and put at over 700 years, no measurement behind the round number. This page maps 27 remarkable trees across 18 cities in Slovakia, each one researched and verified. The oldest of them is The Oak of Dubinné in Dubinné, at at least 800 years, possibly older.
The better-documented tree is a plainer oak in Dubinné, near Bardejov, hollow enough that the wood which would date it has rotted away, leaving a working estimate of at least 800 years and the country's own claim to its oldest oak. Most of the rest of the oldest trees here are lindens, which is not a coincidence: the lime has been Slovakia's national tree since the 13th century. Hronsek's stand in the yard of a UNESCO wooden church; Uzovská Panica keeps something rarer, a 250-year-old service tree that once marked a property line. Bratislava's own collection reads almost as an inventory of other continents: a Japanese pagoda tree on the Danube embankment, an Empress tree from China, a paper birch that belongs in Canada. 27 trees across 18 places now, and the plainest one, not the castle linden, is the oldest.
