Turku Cathedral is commencing a significant renovation that will begin tomorrow, with plans for it to be completed by Advent 2028, coinciding with the celebration of the cathedral's 800th anniversary. During the renovation, the cathedral will be closed to visitors, and no exhibitions or religious ceremonies such as baptisms and weddings will be held there; these will be relocated to other churches in the area.

The renovation aims to upgrade facilities, enhance accessibility, and modernize building technology that has been in place since a major renovation in the 1970s. Many spaces that are currently inaccessible to the public will become available once the renovation is complete. This significant undertaking will cost approximately 25 million euros and will take two and a half years to complete, with the next major renovation not anticipated until at least the 2070s.

Updates on the progress of the renovation can be followed through the cathedral's official website, where further details and milestones will be shared. The project not only marks a critical investment in preserving the cathedral’s historical significance but also aims to enhance the visitor experience and service provision for the local community once the renovations are finished.
