The Dome is the main church of the Swedish lutheran church (which was the state church until the separaion between church and state just before year 2000). It's doors are mostly open so that you can go inside and admire the altar and organ among other things.
Some times there are also free concerts in the church.
DO remember that the lawns surrounding the church is the last resting place of many people even though there are no tombstones, so don't walk on the grass.
