Stortorget is the main square in Karlskrona city located on the island of Trossö. It is centrally located on the highest point of the island and surrounded by monumental buildings including the Fredrik Church, Holy Trinity Church, and Town Hall, which are part of the Naval City of Karlskrona World Heritage Site. The square measures approximately 200x100 meters but its dimensions are partially obscured by the Frederick Church in the middle. It is paved but contains some grassy and treed areas. In winter it is mostly used for driving and accessing nearby buildings, while in summer it hosts many fairs and music festivals.
