ABSTRACT
Most of Poland’s medieval roof constructions have been preserved in Toruń, prompting the authors to attempt to characterise medieval construction timber in Toruń. The following questions were asked: Where did the building material come from? What types of wood were used? How was the building material transported? What sections and tools were used? The research shows that the material came from the nearby forests and from remote areas from which it was transported by rafts to Toruń. It was pine and oak wood. A whole tree, half-tree, cross-tree, and sixth of a tree were used as building materials. A whole tree was pre-treated with an axe and then smoothed out with a carpenter’s hatchet. A half-tree, cross-tree, and sixths of a tree were obtained by sawing the whole tree. The research made it possible to characterise the medieval construction timber in Toruń.
