In the following passage the word “roland” is used to indicate some central fixture of a town that is related to trees (or so I take it). I can’t find the definition of this usage anywhere, though (only the etymological meaning of “famous land” and a celebrated Paladin).
Does anyone know the definition of “roland” in this context? https://books.google.com/books?id=Y6BQgsKTBGoC&pg=PA18&lpg=PA18&dq=hewn+roland&source=bl&ots=Fx3VQFt2EU&sig=ACfU3U3vfXgsqV_buPxXjGFL9cSF1R746Q&hl=en&sa=X&ved=2ahUKEwjsjNz_kMfyAhVEZM0KHbQSDaUQ6AF6BAgrEAI#v=onepage&q=hewn%20roland&f=false
