The cannon was found in Upesgrīva, in the municipality of Mērsrags, on the left side of the River Grīva at a depth of about 1 meter. It was found by employees of the Smiltene road construction company 8 CBR, performing the construction work of the bridge across the River Grīva.
The cannon found was gifted to the Roja Fishing Museum.
Experts have concluded, after examining photos, that this could be a 17th-century cannon, according to Elīna Orna, head of the regional division of the National Heritage Board.
To find out more about the origin of the cannon, the Roja Fishing Museum will work with specialists from the War Museum and call restores to clean up the object.
“There was once an iron kiln near Upesgrīva, possibly a relation, but it is not yet sure to claim,” Indriksone told LSM.lv.
