The former water mill Lyckeby Kronokvarn dates back to the 18th century. It is located at the river Lyckebyån in Lyckeby, a suburb of Karlskrona.
The yellow painted stone building of the Lyckeby Kronokvarn was altered several times in the past, but still corresponds its appearance of the late 18th century. The mill and the old stone bridge over the Lyckebyån are architectural monuments since 1995. Both buildings are part of the World Heritage Karlskrona.
Lyckeby Kronokvarn was built 1710 to 1721 and provided flour to two state-owned bakeries on Stumholmen and Trossö in Karlskrona exclusively. There, the flour was processed into food for the fleet.
