The red stained glass window in the Holy Sepulchre is an artwork by Giorgio Andreotta Calò (Venice, 1979) and refers to the layered past of the Oude Kerk. It emphasises the origin of the room it is situated in: the Holy Sepulchre Chapel. This chapel was built in 1515 as 'prope sepulchrum domini' (the tomb of Christ). It's a replica of the Holy Sepulchre Church in Jerusalem, where a red light is permanently shining to guard the tomb of Christ.
The installation of the window caused controversy and even a lawsuit. It was therefore decided to further discuss the work and the changing meaning of heritage. Starting from the installation, a conversation is organised at the Oude Kerk every 21st of June, the longest day of the year.
