 abstract={This paper discusses an assemblage of artillery projectiles discovered in 2012 in the course of archaeological works in the basement of remains of the Medieval High Turret in Olsztyn (Masuria – north-eastern Poland). 113 cannonballs were found altogether, out of which 89 were made from erratic boulders, while the remaining ones were made from well-fired clay. Apart from a discussion on these finds, a analysis of stone raw material used for their manufacture was carried out. Furthermore, it was attempted at identifying types of cannons stored in this part of Olsztyn’s fortifications},
