While the sun may be reluctant to rise as winter settles in on Helsinki, the aroma of mulled wine, or glögi, and shop window decorations warm the heart as the holiday season approaches. People take advantage of pikkujoulu, or "little Christmas," when they celebrate in pubs and restaurants, because Christmas is normally a quiet family affair. Despite the fact that the temperature drops below minus 10 degrees Celsius at this time of the year, the atmosphere still remains one of warm conviviality. Even when the temperature drops, shops and restaurants gleam with a warm glow, and Finnish structures are known for their ability to withstand the worst frost. When you add carol concerts in churches to the mix, it's hard to believe Helsinki wasn't built for the sole purpose of celebrating Christmas.
