The Hata-men Gate owes its name to Hata, the Mongol Prince, whose palace was situated nearby. This gate offered visitors and traders entrance to the city from the southeastern part. The gate was dismantled in the 1960s during the construction of Beijing's Second Ring Road. The Hata-men Gate owes its name to Hata, the Mongol Prince, whose palace was situated nearby.
