The gates are the entrance to Seoul and the first stop of the collection. The red buildings from Fig. 1 to Fig. 6 are free of charge. Tickets are required to enter the red inner hall. There are booklets for collecting stamps in the customer service center outside the gates. Simplified, traditional, Japanese, English and Korean versions are available. There are 25 small and 2 large chapters. If you want to cover them, you have to enter the inner hall and stamp 6 stamps. After collecting, you can exchange gifts at the service center where the booklet is collected. You can also ask the staff to stamp the emperor's stamp for you (see the last picture). Seal stamping is an exceptional excitement!
