I apologise for the grossly over enlarged image above - but I thought this light was interesting enough to justify inclusion in spite of the rubbish photograph.  There are quite a few of these lights in Norway that do an excellent job of imitating small churches or chapels - the "belfry" like structure at the apex of the front gable of the building is not, in fact, the lantern but once contained a fog bell that has now been removed.  The lantern is in actually located about half way down the nearest corner of the building and is only just visible in this shot.  The lighthouse is situated at the end of a short pier at the north tip of the island of Heggholmen in the inner Oslovjord quite close to the city of Oslo itself.  The light marks a secondary channel used by small vessels entering the harbour of Oslo.  The lighthouse is now preserved as a historic monuent.
