Arctic churches are usually a landmark, sometimes the best building around; most look like this: wooden made, a rectangular body , a single bell tower on the front face, walls coloured red, blue, brown, gray - in general an attractive and rather joyful building, not a dark heavy one.
Inside, a single nave, columns are rare, no chapels, transept in a few, and a modest altar. Now and then, a side chapel, a vestibule or covered entrance, some woodwork.
