What is the oldest tree in Dresden?
The oldest tree in Dresden is the Kaditzer Linde, a large-leaved lime in the churchyard of the Emmauskirche in Kaditz, and the city itself declines to say how old. Its sign calls the tree many centuries old and then adds a thousand years with a question mark, because a fire in 1818 destroyed the side of the trunk facing the parsonage and no ring count has been possible since. What stands there now is a half shell over nine metres round, held up on the inside by former roots that turned into supporting stems. Estimates in the literature run from 500 to 1000 years. Its nearest rival on this page is the Rieseneiche in the Sauerbusch, a pedunculate oak in the Dresdner Heide that a forest record of 1679 already listed as a boundary marker, estimated at up to 700 years. Next comes the lime on the Laubegast riverbank, planted or sown around 1680. Just over the city line in Freital, the sources put the Grenzeiche anywhere between 1570 and 1770, and the Plague Oak of Pesterwitz went in in 1681. If you know of a dated study that narrows the lime's age, tell us.
Dresden keeps an official register of natural monuments, Naturdenkmale, published as a public Wikipedia table and cross-checked for five trees here against Stadtwiki Dresden. At least twenty-one of the thirty-two trees on this page carry that designation; the Babisnau poplar holds it from its own district, and the Plague Oak of Pesterwitz and the Grenzeiche from the town of Freital. The Splittereiche is protected as part of the listed Grosser Garten; the Luthereiche in the Dresdner Heide and the Moreau Oaks are Saxon Kulturdenkmale, and the Luther Oak of Kleinluga is both. The Saengereiche, the Bismarckeiche and the Pillnitz camellia have no official designation. The Albertplatz plane, the Fetscherplatz oak, the Räcknitz horse chestnut and the Heide pine were all protected on 3 January 1985; the Trinitatisplatz oak waited until February 2024. The Kaditzer Linde, probably the oldest, carries a range, because its trunk has been too damaged for too long to be counted. Several other ages come from a recorded planting date, which beats a growth-rate guess but is not a ring count; the Schulmeisterlinde has its planter's own entry of 1622 in the church chronicle. The Brauteich oak and the Konigsbrucker Strasse elm have no age recorded.
