The Oldest Plane of Bahçeköy 1,300-1,400 years
Bahçeköy, Sarıyer. Istanbul's oldest living thing predates the city's Ottoman name by seven centuries.
Before the London plane existed, its eastern parent was already the most storied shade tree in the world. This page maps every oriental plane on the site, 29 so far across 14 cities.
Hippocrates is said to have taught medicine under an Oriental plane on Kos, Herodotus tells of a Persian king who halted an entire army to decorate one, and across Greece, Turkey and the Balkans the village square and the plane above it grew up as a single institution. The species hollows as it ages without weakening much, which lets individual trees pass five hundred years while whole communities hold meetings, weddings and cafes inside and beneath them. The Oriental planes mapped so far include spring-side giants that predate the towns around them, oldest first.
Jardin des Plantes, 5th arrondissement. In 1785, four years before the Revolution, the naturalist Buffon planted three oriental planes in the garden he had run for half a century.
8th arrondissement. The thickest tree in Paris has a waistline of seven metres.
Villa Borghese, Pinciano. Nine trees are what remain of the eleven Cardinal Scipione Borghese planted here four centuries ago.
Trastevere, at the foot of the Gianicolo. Two oriental planes here are older than the university that now owns them.
Bahçeköy, Sarıyer. Istanbul's oldest living thing predates the city's Ottoman name by seven centuries.
Bahçeköy, Sarıyer. Seven trunks that are actually one tree share a single root system at this bend in the Bahçeköy forest.
Beykoz. Ottoman sultans hunted on this exact meadow, which is why locals still sometimes call it Hünkar Çayırı, the Sultan's Meadow, instead of its official name.

Alemdar, Fatih. A stone was lodged inside this tree's bark for roughly three centuries, and until about ten years ago you could still see it.
Beyazıt, Fatih. A tree in Istanbul has had the same downstairs neighbour for 58 years.
Çengelköy, Üsküdar. This tree spent a night on the ground and got back up.
Trinity College, Dublin 2. Two plane trees in New Square have outgrown almost everything else on Trinity's campus, and both went in around 1834, when the college was rebuilding this quadrangle.
European Quarter. The thickest tree of its kind anywhere in Brussels stands in a park built over a vanished stream.
Innere Stadt, 1st district. This tree has been quietly absorbing a piece of iron fence for two and a half centuries.
Landstraße, 3rd district. A memorial stone at its base calls this tree the Jacquin-Platane, but almost nobody in Vienna uses that name.
Innere Stadt, 1st district. Vienna named this plane tree after an empress who famously disliked Vienna.
Kaisariani, Mount Hymettus. A monastery on Mount Hymettus has drawn people to the same spring for over two thousand years, long before the Byzantine monks who gave Kaisariani its name and its 11th or 12th century church ever arrived.
Syntagma. Almost two hundred plane trees went into the ground around the Zappeion in 1857, two decades before the neoclassical hall they now surround had even been designed.
Kefalari, Kifisia. Kifisia was ancient Athens' summer retreat long before it became modern Athens' wealthiest suburb, and the plane trees shading Kefalari Square are the clearest living link between the two.
Chiaia. Naples's seafront garden holds five of the twenty-six trees the Campania region has catalogued as monumental across the whole city, and this Oriental plane, standing beside the Fontana dei Leoni near the garden's street boundary, is among the most substantial: 18 metres tall with a trunk 428cm across.
San Lorenzo. The tree standing today in the Cloister of the Platano is not the tree the cloister was named for, though it is, in a sense, the same organism.
Malpighi. This plane tree grows in a garden raised more than four metres above the surrounding piazza, a quirk of geography with a specific origin: the ground was once known as the Cavallerizza, a riding ground used from 1612 for horsemanship and public events, before the noble Rusconi family converted it into a private garden around 1825 and planted, among other trees, this Oriental plane.
City centre. Edward Pococke spent years in Aleppo and Constantinople as an Oxford scholar sent to master Arabic manuscripts, and returned in 1636 to become the university's first Regius Professor of Hebrew and Laudian Professor of Arabic.
City centre. Edward Daniel Clarke, a Jesus College fellow and later Cambridge's first professor of mineralogy, spent the years around 1800 travelling through Greece, Egypt and the Ottoman Empire, a journey that eventually filled six published volumes and made him one of the era's best-known explorer-scholars.
Trsteno. Around 500 years ago, a sea captain remembered as Florio Jakob Antunov sailed home to Trsteno from Constantinople with five young plane tree saplings and planted them beside a spring on the village's main square.
Elden. The thickest Oriental plane in the Netherlands stands beside the smallest, whitest church in Arnhem, and the two have shared roughly two centuries of the same ground.
Kastra, Ano Poli. At the corner of two narrow streets below Thessaloniki's Byzantine walls stands a tree old enough to have watched the Ottomans arrive.
City centre. This plane tree has spent three centuries next to one of the more improbable ruins in central Thessaloniki: the palace the Roman emperor Galerius built for himself around 300 AD, excavated directly beside the square where the tree now stands.
Waterfront. Standing across the square from the White Tower, Thessaloniki's best-known monument, this plane tree is younger than its two counterparts in Kastra and Navarino Square, core-sampled at around 235 years old, yet it is the largest of the four by a clear margin: 26.4 metres tall with a trunk 140 centimetres through at chest height, taller and thicker than the 828-year-old tree in the old town above it.
Ano Poli. The youngest of Thessaloniki's four core-sampled ancient planes, at around 205 years old, grows at the entrance to a house built in the final years of the Ottoman era and preserved today as the Atatürk Museum, the birthplace, by tradition, of the Turkish republic's founder, and now free to enter for anyone who visits.
