This quadriga on top of the Brandenburg Gate is much more impressive as the night moves in, making the cloudy sky a beautiful mix of blues and pinks. Also, that is when the lights pointing at the work of art are turned on, creating a nice glow. Behind the Gate is the famous Tiergarten of Berlin—an expansive park excellent for walks and biking.
A quadriga (Latin quadri-, four, and iugum, yoke) is a car or chariot drawn by four horses abreast (the Roman Empire’s equivalent of Ancient Greek tethrippon). It was raced in the Ancient Olympic Games and other contests. It is represented in profile as the chariot of gods and heroes on Greek vases and in bas-relief. The quadriga was adopted in ancient Roman chariot racing.
They were emblems of triumph; Victory and Fame often are depicted as the triumphant woman driving it. In classical mythology, the quadriga is the chariot of the gods; Apollo was depicted driving his quadriga across the heavens, delivering daylight and dispersing the night. Source: Wikipedia.
