Finland's capital is aglow with colourful lights and lasers piercing the black winter skies and lighting up downtown buildings providing a much-needed burst of illumination during the darkest days of the year.
Light and sound installations at the Helsinki Lux Festival brought crowds at the city landmarks joined by lanterns hanging in trees along a path of light bordering the frozen Baltic Sea through parks and on city footpaths, where the shortest period of daylight in midwinter is about five hours long.
