Cannonballs from the Olsztyn turret

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
