What is "samcheonggak"

Samcheonggak ( Hangul:삼청각 Hanja:三淸閣) is a small Korean-style mountainside resort in Seongbuk-dong, Seongbuk-gu, Seoul. Samcheonggak is near Cheong Wa Dae, the official residence of the President of South Korea, so the surrounding forest remained undeveloped during Korea's miraculous economic growth.
