Gate of Divine Prowess -- Shenwumen in Chinese

Introduction of Gate of Divine Prowess
Gate of Divine prowess (Shenwumen) is the north gate of the Forbidden City. On its tower were bells struck in the morning and drums beaten in the evening in the old days to mark time. The empress and imperial concubines left the palace through this gate to attend the ceremony of starting silkworm-breeding season.

Chongzhen, the last emperor of the Ming Dynasty, went through the Gate of Divine prowess to the Coal Hill to hang himself in 1644.
