Seoul has many observatories that help you appreciate sceneries. One of them, Jeongdong Observatory, is located on the 13th floor of Seoul City Hall Seosomun Building near Exit 1, Seoul City Hall Station, Subway Line 1. It is open every day from 9:00 am to 9:00 pm on weekdays and from 9:00 am to 6:00 pm during weekends and public holidays. Admission is free.
The observatory on the 13th floor has a wonderful view. You will feel good while appreciating the outside view over coffee at a café there. I remember being surprised at the existence of such a place within a local government office. You can see downtown sceneries including tall buildings at a distance. You will like the autumnal landscapes of nearby Deoksugung Palace including Seokjojeon Hall and Junghwajeon Hall. The coexistence of ultra-modern buildings and olden-day palaces is an advantage offered by Seoul. Especially, Seokjojeon Hall, a western building built in the early modern period, looks like a connecting link between the other traditional palace buildings and nearby modern building. I couldn't see the view because it was a cloudy day with a drizzle of rain; on a sunny day, however, you can enjoy a vivid landscape. I thought it was a nice way of appreciating colored tree leaves. In fall, the colored tree leaves harmonize well with the colors of the palace buildings.
Sipping a cup of coffee on a seat close to the wide windowpane was a nice experience. On the windowsill was a plate containing information on Deoksugung Palace along with the names of its buildings. I thought it was a nice way of studying history, looking at actual buildings and texts. The chronology table set up on the left wall of the place shows the names of buildings in Jeong-dong along with their history. You can also check out buildings of different style including traditional palaces and Seoul City Hall.
Later, walking along the street deeply imbued with autumnal atmosphere, I checked the names of the buildings in the area. It was a nice way of spending a leisurely afternoon. I thought it would be great to visit here to record how Deoksugung Palace looks like whenever the season changed.
