Palaces of ice
Glowing sculptures stand out against the night sky during the 30th Ice and Snow Festival in the northern Chinese city of Harbin.
Almost 10,000 workers were employed to build the glittering structures, according to organisers. The mammoth task required some 180,000 square meters of ice and almost as much snow.
Braving temperatures that dipped as low as minus 21 degrees Celsius (minus 5.8 degrees Fahrenheit), a swimmer leaps into an icy pool in Harbin’s partially frozen Songhua River in the run-up to the festival.
Many others followed suit on the opening day of the event. Organisers said around 700 people took part in the Harbin Ice Swimming Competition as the festival launched on January 5.
