At the west side church in Porsgrunn (dated to 1758 CE), it is possible to find God’s name two places. When you approach the altarpiece, you can clearly see the Hebrew letters YHWH at the top of the altarpiece.
But inside the sacristy (the priest’s anteroom), there is another altarpiece, with the writing “Jehova”. The text can be difficult to spot at first sight.
