Stuttgartで最も古い樹木はどれですか。
The oldest tree in Stuttgart with a measured estimate is the Ash at Schloss Solitude, a European ash with a trunk 6.72 metres round, put at roughly 250 years by the German tree register baumkunde.de. Several other designated trees on this page, including the Hutteneiche, carry no recorded age at all and could in principle be older.
The Solitude ash's age comes from baumkunde.de, a dendrological register that measured the trunk at 6.72 metres round in May 2026 and estimated 250 years from that girth, a figure this page carries as a band, 200 to 300 years, rather than a false-precise number. It stands on the open lawn in front of Schloss Solitude, a baroque hunting lodge whose grounds are free at any hour, part of a designated group with two unmeasured sycamore maples. Nothing else on this page has a comparable reading. The Hutteneiche carries a story to 1515, when Duke Ulrich of Wurttemberg is said to have hanged his stable master from an oak on this spot, but no source claims the standing tree is that same individual, so no age follows from the legend. The Oberdorfplatz Mulberry and the Kurpark's three bald cypresses are documented only by their 2003 designation date, which records when the city started protecting them, not when they were planted. Where a tree's own age is unknown, this page says so rather than guessing, and asks anyone who can help to tell us.
