The gate was the entrance of drinking water for the Emperor, coming from the Jade Spring Hills to the west of Beijing.
The Beijing North railway station is in the Xizhimen area.
The main Xizhimen Bridge, built also in the 1970s, once stood a rather frightening 5.5 m (it was then, and still is now, for the record, the tallest bridge on the 2nd Ring Road) and had three layers, with the top layer acting as a roundabout.
In 2008 due to the Olympic Games, a reform in Xizhimen Transportation hub, was finished, a masterplan willing to integrate the new Xizhimen, Offices and Commercial building, with the Xihuan Plaza, and both train and subway station.
Several Chinese and International Companies took part on the design and construction of the plan.
