Seventeen arches at sunset

When it's winter solstice time in the Northern Hemisphere (where the North Pole has its maximum tilt away from the Sun), the setting sun shines under the Seventeen-Arch Bridge of the Summer Palace in Beijing, causing this romantic glow. In the 18th century, during the reign of the Qing dynasty of China, Emperor Qinglong ordered the construction of this 2.8 square kilometre collection of gardens, lakes, and various structures including temples and small palaces. Today it's one of Beijing's premier attractions and will be crowded today with visitors headed to the bridge in time for sunset.
