The Sankt Laurentii Church Tower is a striking medieval relic in the centre of Roskilde — a tall Romanesque brick tower that stands alone, the last remnant of a parish church demolished after the Reformation. When the church was pulled down in the 16th century, the tower was left standing, perhaps as a landmark or perhaps simply because it was too solid to bother removing.
The tower is visible from the main shopping street and makes an arresting sight — a medieval structure in the middle of an ordinary town centre, with no church attached. It's a good illustration of how dramatically Roskilde shrank after it lost its status as the Danish capital: at its medieval peak the town had at least seven churches; today the tower is one of the few physical reminders of most of them.
