What is the oldest tree in Bologna?
Bologna's oldest precisely dated tree is one of the monumental plane trees of the Parco della Montagnola, planted around 1820 during Giovanni Battista Martinetti's Napoleonic-era redesign of the city's first public park, making it roughly 206 years old. It stands free to visit in the historic centre, a short walk from Via Indipendenza.
Bologna's monumental trees are documented through Italy's national register (the Alberi Monumentali d'Italia list, created under a 2013 law) and the Emilia-Romagna region's own parallel catalogue, together covering eight specimens within the city itself. Among those, the oldest with a precisely traceable planting is one of the large plane trees in the Parco della Montagnola, the city's first public park, laid out from 1805 under instructions passed down through Napoleonic administration and redesigned by the architect Giovanni Battista Martinetti. Several of the park's planes from that era survive today with trunks exceeding four metres around. The park is free and open daily.
