Warsaw's register of natural monuments gives this oak a first name. Karol is a pedunculate oak of 24 metres, and it is not a park tree: it grows on the pavement of ul. Popiełuszki in Żoliborz, four or five kilometres north of the centre. The state protected it on 22 October 1982, registered on its own rather than as one of a group, which means the monument is this single tree and nothing around it. More than forty years later it is still standing on the same stretch of pavement. Get the address right when you go. Number 15 holds two protected oaks. The public nursery at that address has its own, entered in the register separately and never given a name, so the pair are easy to mix up on the ground. Karol is the one with the name; its neighbour carries only a code. The height is on record and almost nothing else is. No published source we could find gives a girth or an age, which for a named oak on a Warsaw street is a strange gap. If you have put a tape measure around it, or you know when it was planted, tell us.
In fruit
September to October: acorns drop, and a good mast year buries the ground in them
The line is our estimate of how much there is to see, not a measurement. Typical for this species where this tree stands; exact weeks shift with the year.
ul. ks. Jerzego Popiełuszki 15, Żoliborz, WarsawYou can recognise it by its name plaque, the tree called Karol, at an address that also holds a second, unnamed protected oak. It stands at ul. Popieluszki 15, Zoliborz.
Free, public street tree in Żoliborz on ul. Popiełuszki; Wikimedia Commons categorises it explicitly as a "street tree in Warsaw". It stands near (not necessarily inside) Żłobek nr 24, a public nursery at the same street address which has its own separately-registered oak (a different, unnamed tree, kodinspire ...3078) -- the two should not be confused
Żoliborz district, roughly 4-5km north of Warsaw city centre and about 4.5km from the nearest currently-published Warsaw tree (war_003, Wola); would start a new cluster rather than join the existing one
