ABSTRACT
Material culture around warships can be addressed in multiple ways. One well-preserved group of items consists of iron cannons. They can be discovered on the seabed as stray finds, missing the original context of a ship, or as part of a wreck site. Our study focuses on the sea fortress Suomenlinna, known from the reuse of cannons as a fence around Suomenlinna's church. The same cannons could have been used either on the fortress or on board a ship. We studied one barrel and carriage, and our primary question was to discover if the original location of the cannon was on the shore as part of a coastal defence system or on board a Swedish warship localised 50 metres away from the cannon site.
