It is the darkest season in the northern hemisphere, and here in the very north the days still shorten day by day for a little time longer. After winter solstice it will slowly get better, although winter proper is still ahead. A good excuse for nice Christmas lights then..
The official Christmas shopping street of Helsinki, Aleksanterinkatu has beautiful lights in the winter.
Shopping centers also have pretty decorations, ’tis the season for spending money after all..
