Unlike other palaces, Deoksugung and Changgyeonggung are said to be open at night.
It snowed today, so I really wanted to see Changgyeonggung at night, covered in white snow, so I went there after work.
Honghwamun Gate of Changgyeonggung Palace
The first time I learned that the palaces were closed when it snowed heavily.
Seonyudo Park was open.
