The article investigates the complex nego-tiation process regarding the renovation of St Catherine's church in St Petersburg. Additionally, the goal is to gain novel understand-ing of how former religious spaces can be trans-formed and highlight the various significances these structures may possess in different con-texts, particularly at the junction of religion and cultural heritage.

The article examines the reasons and arguments for renovation, as well as the progress that has been made to date. Additionally, it explores the role of Sweden in Russia through the perspectives of various stakeholders, including members of the congregation, diplomats, politicians, architects and priests.
