Deshengmen

It is one of Beijing's few preserved city gates and now stands as a landmark on the northern 2nd Ring Road.

[1] The original gate complex, built in 1437, was composed of three structures – the gatehouse, archery tower, and barbican.

They overlook the northern city moat, and house an ancient coin exhibition inside.

The gate complex is surrounded by the Deshengmen bridge, a rotary overpass that channels traffic from the 2nd Ring Road to the Badaling Expressway.

In traditional times, the imperial military would march out of Beijing through Deshengmen, and return through Andingmen, the Gate of Peace and Stability.
