If you’ve seen the castle and have more time to kill, walk south along the line of the river, past impressive remnants of the old city walls, to this square behind Hotel Stary Malbork. This scrappy park isn’t much to look at, but around its edge are commemorative stones placed by keen international speakers of Esperanto from as far away as Korea and Congo, in honour of the world language invented by Ludwig Zamenhof.
There’s a monument to the great man in the middle of the park. The explanatory signage is in Polish…and Esperanto, naturally.
