Seoul Gusan Library sits in the middle of a residential area in Gusan-dong, built by connecting three villas while keeping their original exteriors. It holds books for readers from age 0 to 100, including comics corners by age group and titles in the arts. Small rooms and corridors link together like a maze, and the library stays open until 10 p.m. on weekdays. The parking lot is full even on weekday mornings, and the accessible parking space is blocked.
