This is Masthuggskyrkan (Mast-maker-church). In the photo below you can see how masts make up the upper section in the background.

The church was almost intentionally blown up during the second world war. It provided a distinct landmark for enemy ships that might come into the harbour.

Fortunately it wasn’t. It provided a panorama view of the city of Gothenburg (Göteborg) and Ewa and I went up to see the fireworks.

Afterwards there was a simple service.
